New Yorker Report on Medical Problems of U.S. Diplomats in Cuba

The November 19, 2018, issue of The New Yorker has a lengthy article about the medical problems experienced by some U.S. diplomats in Cuba starting in late 2016 (and after the U.S. presidential election). [1]

The conclusion, however, is the same as previously reported: some U.S. personnel did suffer injury and the U.S. Government has publicly stated it does not know the cause or perpetrator of these injuries.[2]

But the article does provide greater details about many of the victims having been CIA agents and about the U.S.-Cuba interactions over these incidents.

Continuing Controversy Over Medical Problems of U.S. Diplomats in Cuba (and China)

Since late 2016 some U.S. diplomats (now 26 in number) have complained about various medical problems that surfaced while they were serving in Cuba.[1]

The U.S., however, continues to assert publicly that despite subsequent investigations the U.S. does not know what or who caused the problems. Most recently, on September 6, 2018, at a House hearing, Kenneth H. Merten, Acting Principal Deputy Assistant Secretary, Bureau of Western Hemisphere Affairs, stated that the “Department does not currently know the mechanism for the cause of the injuries, the motive behind these attacks in Cuba, when they actually commenced, or who is responsible.” At the same hearing, Charles Rosenfarb, the State Department’s Medical Director, testified, “We’re seeing a unique syndrome. I can’t even call it a syndrome. It’s a unique constellation of symptoms and findings, but with no obvious cause.”[2] (Emphases added.)

Cuba, on the other hand, continues to assert that it did not cause the problems and indeed that there is no scientific basis for any contention that the diplomats suffered any kind of medical issues. For example, in June 2018, a Cuban diplomatic official said that Cuba had “challenged the U.S. on the use of the word ‘attack.’ “There is no evidence of a weapon, there is no evidence of a source, nobody can point to motivation and yet they continue to use the word ‘attack.’ We see it as politically motivated.’” He also noted that neither American nor Cuban experts had been able to determine what caused the symptoms. He renewed concerns that the Trump administration is using the incidents as an excuse to roll back U.S.-Cuba rapprochement started under the Obama administration.[3]

In the meantime, at least the following four theories about causation of the medical problems have emerged.

University of Pennsylvania Theory[4]

Physicians at the University of Pennsylvania examined the affected diplomats and in an article in the Journal of the American Medical Association (JAMA) asserted the following key findings:

The patients “appeared to have sustained injury to widespread brain networks.”
The patients have experienced “persisting disability of a significant nature” involving “hearing, vision, balance and brain symptoms similar to the brain dysfunction seen with concussions, but without histories of head trauma.”
In most cases, the affected diplomats reported hearing a loud, painful noise that they later associated with their symptoms, but the physicians concluded, “There is no known mechanism for audible sound to injure the brain” and “it is currently unclear if or how the noise is related to the reported symptoms.”
“Viruses or chemical exposures are unlikely,” but could not be “systematically excluded.”
“Advanced MRI scans spotted a few changes in some patients in what are called white matter tracts,” but these might be attributed to previous events.
“Several of the objective manifestations consistently found in this cohort,” including vision and balance abnormalities, “could not have been consciously or unconsciously manipulated.”

In August 2018 JAMA published letters from 10 neurologists and doctors from the United States, the United Kingdom and Germany that questioned the conclusions of the University of Pennsylvania report. They said it could have misinterpreted the result of medical tests or ignored disorders that cause symptoms among a large group of people, as psychological factors.

Smith and two colleagues published a response that said they are performing “advanced neuroimaging studies” of the patients and are “hoping to identify structural brain changes that may underlie the neurological manifestations.”

University of Michigan Theory[5]

A team of computer scientists from the University of Michigan’s Security and Privacy Research Group in March 2018 concluded that “if ultrasound played a role in harming diplomats in Cuba, then a plausible cause is intermodulation distortion between ultrasonic signals that unintentionally synthesize audible tones. In other words, acoustic interference without malicious intent to cause harm could have led to the audible sensations in Cuba.” The conclusion of the research paper itself also states, “our experiments do not eliminate the possibility of malicious intent to harm diplomats.” (Emphasis added.)

If I correctly understand this theory, the audible sound similar to that heard in Cuba requires at least two ultrasound sources that interfere with each other and this suggests that the audible sound was accidental and not intended. This supports Cuba’s consistent assertion that it did not intend to do anything to harm the American diplomats, an assertion that makes obvious sense from Cuba’s own self-interest of avoiding antagonizing the U.S.

Microwave Theory[6]

The lead physician and author of the University of Pennsylvania report, Dr. Douglas H. Smith, recently told the New York Times that “microwaves were now considered a main suspect and that the team was increasingly sure the diplomats had suffered brain injury.” He added, ““Everybody was relatively skeptical at first [but] everyone now agrees there’s something there.”

According to the Times, “Strikes with microwaves, some experts now argue, more plausibly explain reports of painful sounds, ills and traumas than do other possible culprits — sonic attacks, viral infections and contagious anxiety. In particular, a growing number of analysts cite an eerie phenomenon known as the Frey effect, named after Allan H. Frey, an American scientist. Long ago, he found that microwaves can trick the brain into perceiving what seem to be ordinary sounds.” Moreover, “scientists have known for decades that the brain can perceive some microwaves as sound.” Indeed, “The false sensations, the experts say, may account for a defining symptom of the diplomatic incidents — the perception of loud noises, including ringing, buzzing and grinding. Initially, experts cited those symptoms as evidence of stealthy attacks with sonic weapons.”

Beatrice Golomb, a professor of medicine at the University of California at San Diego, is a leading proponent of the theory that pulsed microwaves could explain the symptoms. She has authored a paper that will be published in coming days in the journal Neural Computation. The symptoms experienced by the Cuba patients match symptoms in other people who are “electrosensitive,” according to her analysis, which relies on the JAMA study and news reports.

Asked about the microwave theory, the State Department said the investigation had yet to identify the cause or source of the attacks. And the F.B.I. declined to comment on the status of the investigation or any theories. In addition, In addition, members of Jason, a secretive group of elite scientists that helps the federal government assess new threats to national security, say it has been scrutinizing the diplomatic mystery this summer and weighing possible explanations, including microwaves.

James C. Lin of the University of Illinois, a leading investigator of the Frey effect, described the diplomatic ills as plausibly arising from microwave beams. Dr. Lin is the editor-in-chief of Bio Electro Magnetics, a peer-reviewed journal that explores the effects of radio waves and electromagnetic fields on living things. In his paper, Dr. Lin said high-intensity beams of microwaves could have caused the diplomats to experience not just loud noises but nausea, headaches and vertigo, as well as possible brain-tissue injury. The beams, he added, could be fired covertly, hitting “only the intended target.”

In February, ProPublica in a lengthy investigation mentioned that federal investigators were weighing the microwave theory. This article also mentioned that a wife of a member of the embassy staff had looked outside her home after hearing the disturbing sounds and had seen a van speeding away.

Kenneth R. Foster, a professor of bioengineering at the University of Pennsylvania, has studied microwave phenomena while working at the Naval Medical Research Center in Bethesda. Foster, who was not involved in examining the diplomatic personnel, said that the reported illnesses remain mysterious and that he doesn’t have an explanation.

Nevertheless, Foster said, “But it’s sure as heck not microwaves.” Such a theory is “wildly impossible.” According to Dr. Foster, “to actually damage the brain, the microwaves would have to be so intense they would actually burn the subject, which has never happened in any of these incidents.” Foster added that there is no technology capable of using microwaves to produce the kinds of symptoms that the U.S. diplomats have experienced — and not for lack of trying. “Actually the Navy was interested in seeing whether this could be used as a weapon, and we spent a lot of time thinking about it, but the phenomenon was simply too weak to be of any conceivable use.”

A rejection of this theory also was voiced by University of Cincinnati neurologist Alberto J. Espay, who said, “Microwave weapons is the closest equivalent in science to fake news.”

A Cuban diplomat, Fernández de Cossío, Director for United States at Cuba’s Foreign Ministry, insisted that the microwave theory cannot explain the symptoms suffered by the U.S. diplomats in Havana. Mr. Fernández de Cossío accused the U.S. of carrying a deliberate political manipulation. On Monday, CNN reported that Dr. Mitchell Valdés-Sosa, a neurologist investigating on behalf of the Cuban government, also dismissed this theory.

The strangest reaction to the microwave theory came in a Washington Post editorial. After reviewing the pros and cons of the theory, it concluded, “the microwave explanation has again raised a question about whether the United States has discovered more than is being said about the perpetrators. If there are known culprits, they should be identified and held to account.”

Neuro-Weapon Theory[7]

A team put together by the State Department to investigate this problem consisted of Dr. Michael Hoffer of the University of Miami and an expert in brain trauma and otolaryngology; Dr. Carey Balaban, professor of otolaryngology, bioengineering and neurobiology at the University of Pittsburgh; and Dr. James Giordano, professor in the departments of neurology and biochemistry at Georgetown University Medical Center, and an expert in “neurotechnology” and its use in the military.

This team independently studied the first tests taken of those affected. And this team believes that the patients likely were hit by a weapon that uses directed energy and is capable of causing a “cavitation” effect or air pockets, in fluids near the inner ear. The bubbles can travel quickly through two pathways that carry blood to the brain from the inner ear — the cochlear and the vestibular — and “function as a stroke,” Giordano said.

Such “neuro-weapons” can be biological, chemical, or in the case of the incidents in Havana, “directed energy weapons.” The team was unable to conclude exactly what method the perpetrators of the attacks used but reduced it to the following possibilities:

▪ Ultrasonic (acoustic) exposures were considered “very possible and probable.”

▪ Electromagnetic pulsing was also described as “very possible and probable.”

▪ The team reported that the use of microwave energy was possible, but “unlikely.”

Conclusion

I am not a scientist or medical doctor and am unable to evaluate the merits and demerits of the above theories. I, therefore, specifically invite comments with additional information or thoughts.

But I also confess that I am amazed that after nearly two years the official U.S. public position is an inability to identify the cause or perpetrator.

U.S. Senate Hearing on Medical Problems of U.S. Diplomats in Cuba

On January 9, a subcommittee of the U.S. Senate Foreign Relations Committee held a hearing entitled “Attacks on U.S. Diplomats in Cuba: Response and Oversight.” The Subcommittee on Western Hemisphere, Transnational Crime, Civilian Security, Democracy, Human Rights, and Global Women’s Issues was chaired by Senator Marco Rubio (Rep., FL), a noted critic of normalization of U.S.-Cuba relation, who said the purpose of the hearing was “to establish the facts surrounding the attacks on U.S. diplomats in Cuba, and conduct oversight over the State Department’s handling of the attacks.”[1]

The witnesses were three officials of the U.S. State Department: Mr. Francisco Palmieri, Acting Assistant Secretary, Bureau of Western Hemisphere Affairs; Mr. Todd Brown, Diplomatic Security, Assistant Director, International Programs; and Dr. Charles Rosenfarb, Medical Director, Bureau of Medical Services.

The hearing started with lengthy opening statements by Rubio and the Ranking Member, Bob Menendez (Dem., NJ), both very critical of the Department’s response to these incidents or “attacks.” [2] The hearing itself focused on the following four topics:: (1) the nature of the injuries; (2) the cause of the injuries; (3) the perpetrator of the “attacks;” and (4) the State Department’s appointment of an accountability review board.

The Nature of the injuries

While the symptoms may vary, all 24 of the medically-confirmed cases have described some combination of the following symptoms: sharp ear pain, dull headaches, tinnitus (ringing in one ea), vertigo, visual focusing issues, disorientation, nausea, extreme fatigue. Some have been diagnosed with mild brain injuries similar to what might happen from a concussion.

The cause of the injuries[3]

In early July, the Bureau of Medical Services at the State Department convened a panel of academic experts to review case histories and the test results up to that point. And they arrived at [the following] consensus: ‘the patterns of injuries were most likely related to trauma from a non-natural source.”

Mr. Brown said investigators are considering possible causes other than a sonic attack, including a viral attack. He also said the possibility that someone deliberately infected people with a virus has not been ruled out. Dr. Rosenfarb testified that evidence suggest that( this is “not an episode of mass hysteria.”

Brown also said he would not rule out a sound component entirely. He said there had been an “acoustic element” associated with the sensations and feelings experienced by diplomats who fell ill. He said it’s possible the sound masked some other technology that caused the damage.

Dr. Rosenfarb said investigators are confident that something indeed caused medical harm to the Americans.

“Perplexing” was a frequent word in this discussion.

Perpetrator(s)

Senator Rubio in a Fox News interview before the hearing said Havana is one of the most tightly controlled cities in the world. “There is no way you can conduct sophisticated attacks targeting American government officials in Havana without the Cuban government at least knowing about it.” [4] He repeated this opinion or conclusion at the start and at the end of the hearing.

Accountability Review Board

Senator Rubio obtained admissions from the witnesses that a “serious injury” of at least one U.S. diplomat in Cuba happened no later than May 2017 and that the Secretary of State had not appointed an accountability review board within 60 days thereafter, as required by statute, and indeed had not yet done so.[5]

Acting Secretary Palmieri tried to remedy this apparent breach by testifying that Secretary Tillerson on December 11, 2017, had decided to convene such a Board and that the statutory required notice to Congress was “forthcoming.”

The same question came up later the same day at the Department’s Press Gaggle, [6] when the Department spokesperson, Under Secretary I. Steven Goldstein, initially said, “We are going to create, as we’ve said previously, an accountability review board, and I would expect that we would have the announcements of the chair and the members of the board available for release within the next week.” He then was pressed with a reporter’s question about Senator Rubio’s apparent contention that the Department and the Secretary had violated the law by not making an earlier appointment of such a board. Goldstein had the following response:

“We don’t agree with [the allegation that the law was violated].The assistant secretary today made clear [at the hearing], and we have said too, that it took us time to get the investigation in place. The investigation is continuing, and we believe that we . . . had the authority to determine when the accountability review board should be set in place. I think let’s not lose focus here. There’s 24 people that had injuries, and those people are receiving treatment, and we’ve had over 20 conversations with the people of Cuba. . . . [The] government investigators have been down four times; they’re going down again within the next few weeks. And so our primary goal at the present time is to find out why this occurred, to prevent it from happening again in Cuba and the embassy of Cuba or in any other place where American citizens are located.”
“It took time to set up the . . . board because we were hopeful that we would be able to know what occurred. . . . [T]his investigation has taken longer than we anticipated, . . . but it is now time to go forward. . . . I expect the names [for the Board] to be announced over the next several days.”

Conclusion

Only five of the nine subcommittee members attended the hearing, and the members will be submitting written questions to the witnesses, and there will be classified briefing of the subcommittee. Thus, the complete record will not be available until later. [7]

At the conclusion of the hearing, Rubio said that the following were two established facts: (1) 24 Americans had been harmed while in Cuba and (2) the Cuban government at least knew who was responsible for causing such harm. “The idea that someone could put together some sort of action against them, 24 of them, and the Cuban government not know who did it, it’s just impossible,” Mr. Rubio said. He noted that the Americans in Havana became sick just after Mr. Trump’s election, and speculated that rogue government officials from either Cuba or Russia had sought to create friction between Havana and the new administration in Washington.

Under Secretary Goldstein voiced a similar opinion by saying, “We believe that the Cuban government knows what occurred. So what we’d like to them to do is tell us what occurred.”

After the hearing, Cuba’s diplomat who has been intimately involved in U.S.-Cuba relations , Josefina Vidal, said the hearing was chaired by two Senators (Rubio and Menendez) “both with a vast record of work against better relations between Cuba and the United States, and the promoters of all kinds of legislative and political proposals that affect the interests of the Cuban and American peoples, and only benefit an increasingly isolated minority that has historically profited from attacks on Cuba.” She continued:

“From [the hearing’s] very title “Attacks on U.S. Diplomats in Cuba,” it was evident that the true purpose of this hearing . . . was not to establish the truth, but to impose by force and without any evidence an accusation that they have not been able to prove.”
“The State Department does not have any evidence that allows it to affirm that there have been attacks against its diplomats in Havana, or that Cuba may be responsible, or have knowledge of the actions of third parties.”
“I categorically reiterate that the Cuban government has no responsibility whatsoever for the health conditions reported by U.S. diplomats. Cuba never has, and never will, perpetrate such acts, nor has it or will it permit third parties to act against the physical integrity of any diplomat, without exception. The Cuban government is aware of its responsibilities and fulfils them exemplarily.”
“I affirm that the investigation carried out by Cuban authorities, the results of which the State Department and specialized agencies of the United States have had ample and systematic access to, has shown that there is no evidence at all regarding the occurrence of the alleged incidents and no attack of any kind has occurred.”
“Nothing presented by the government of the United States throughout this period, including today, provides evidence that the health problems reported by its diplomats have their origin or cause in Cuba.”
“We reject the politicization of this matter and the unjustified measures adopted by the United States government, with a high cost for our population, Cuban émigrés and the U.S. people. We also condemn the political manipulation of these events by anti-Cuban elements, who seek to aggravate the bilateral atmosphere, with the sole purpose of returning to a an era of confrontation, with negative consequences for both countries and the region.”
“Cuba is a safe, peaceful and healthy country for Cubans, for foreigners, for accredited diplomats and for the millions of people who visit us every year, including U.S.”[8]

This blogger’s opposition to Senator Rubio’s hostile approach to Cuba has been expressed in a prior post. That approach is against U.S. economic and strategic interests. It provides openings to Russia and the EU, for example, to pursue various developments with Cuba while the U.S. stands on the sidelines. Moreover, that approach contradicts Rubio’s stated desire to support Cuba’s emerging private sector and the Cubans investing and working in that sector.

Senator Rubio also erroneously stated that it is a fact that Cuba has one of the world’s most pervasive surveillance systems in the world and, therefore, has to know if some third-party has perpetrated attacks on U.S. (and Canadian) diplomats. At most that is an allegation or theory, which has been denied by Cuba. Rubio also ignores that whatever security and surveillance system Cuba has undoubtedly is prompted, at least in part, by the long history of U.S. hostility towards the Cuban Revolution, including covert or undercover efforts to promote regime change on the island. Moreover, in its responses to the medical problems of some of its diplomats in Cuba, the U.S. repeatedly has emphasized Cuba’s obligation under the Geneva Convention on Diplomatic Relations to protect other countries diplomats on the island, an obligation that presumably requires Cuba and other nations, including the U.S., to have some idea as to the whereabouts of those diplomats.

Yet More News Regarding the Medically Affected U.S. Diplomats in Cuba

There are more developments regarding the actions and reactions associated with the medically affected U.S. diplomats who had been stationed in Cuba.

The U.S. State Department Spokesperson, Heather Nauert, at an October 4 Press Briefing, responded to Cuba’s criticism of not obtaining sufficient U.S. information about the medical problems of some of its personnel in Cuba. She said the U.S. was “engaged in an investigation, [and] we, as Americans, need to keep a tight hold on a lot of information. We don’t want that information to leak. . . . That information could potentially leak to other parties . . . who may or may not be involved. So, providing information on the investigation could tip off what I’ll just call the bad guys who are responsible for this. We don’t know who or what is responsible. So . . . we wouldn’t want to tip off the bad guys to any information that we have on the investigation. Again, I’m not calling the Cubans – saying that about the Cubans in general, but we wouldn’t want this type of information to leak.” She added, “the investigation is ongoing. The investigation has not yet been resolved, so there is limited information that we can provide at this point.”[1]

On October 5, the Cuba embassy in Washington reported that its 15 diplomats who were ordered for expulsion included all who handled dealings with U.S. businesses. One of them said, “due to this decision, the activities developed by the Economic and Trade Office of the Embassy… will be seriously affected.” Such activities are usually the first step in the process for U.S. companies when they submit trip proposals, seek out counterparts at state-owned enterprises in the centralized economy and obtain business travel visits to travel to Cuba. In addition, the reduction in staffing the U.S. Embassy in Havana will make it more difficult for U.S. companies to find their way in Cuba.[2]

Scientists doubt a hidden ultrasound weapon can explain what happened in Cuba. “I’d say it’s fairly implausible,” said Jurgen Altmann, a physicist at the Technische Universitat Dortmund in Germany and an expert on acoustics. At frequencies higher than 20,000 Hertz, beyond human hearing, ultrasound can damage tissue if produced with enough power, but “ultrasound cannot travel a long distance,” said Jun Qin, an acoustic engineer at Southern Illinois University. The further the sound goes, the weaker it gets. And, noted Dr. Garrett, humidity in a place like Havana would weaken it still more. Infrasound — low-frequency sound that cannot be heard by humans—on the other hand, is even more unlikely. A report by the National Institute of Environmental Health Sciences in 2002 noted that the military had tried to weaponize infrasound, but had not succeeded because it was hard to focus the wavelengths. The primary effect of infrasound on humans “appears to be annoyance,” the report concluded.[3]

Also on October 4, the Senate Foreign Relations Committee held a closed hearing on “Ordered Departure of Personnel from U.S. Embassy in Havana, Cuba.”[4] with an unnamed Senior Official from the CIA plus these three “Briefers” from the State Department: (a) Mr. Christian J. Schurman; Deputy Assistant Secretary Of State And Assistant Director For International Programs; Bureau Of Diplomatic Security with responsibility for “evaluating, managing, and mitigating security threats to, as well as the direction of resources for, more than 240 diplomatic posts within the International Programs Directorate;” (b) Mr. John S. Creamer, Deputy Assistant Secretary; Bureau Of Western Hemisphere Affairs;and (c ) Dr. Charles Rosenfarb, Medical Director; Bureau Of Medical Services. Since the hearing was close, we do not yet know what happened.
