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.
