On September 11, 2018, NBC News exclusively reported that U.S.intelligence agencies have concluded that Russia is “the main suspect” for causing the medical problems of the 26 U.S. diplomats stationed in Cuba. In addition, NBC reports that “the victims [also] include multiple CIA officers, at least one member of the U.S. military, and representatives of other agencies.”
This conclusion is reported to be “is backed up by evidence from communications intercepts, known in the spy world as signals intelligence.” This prompted the U.S. investigation to turn to “the Air Force and its directed energy research program at Kirtland Air Force Base in New Mexico, where the military has giant lasers and advanced laboratories to test high-power electromagnetic weapons, including microwaves. . . Although the U.S. believes sophisticated microwaves or another type of electromagnetic weapon were likely used on the U.S. government workers, they are also exploring the possibility that one or more additional technologies were also used, possibly in conjunction with microwaves.”
NBC News further reports that although “the U.S. believes sophisticated microwaves or another type of electromagnetic weapon were likely used on the U.S. government workers, they are also exploring the possibility that one or more additional technologies were also used, possibly in conjunction with microwaves, officials and others involved in the government’s investigation say.”
On August 14, “the U.S. convened officials from the Energy Department, the National Institute of Health, the State Department and the Canadian government at the Sandia National Laboratories in Livermore, California, according to State Department medical officials. U.S. experts attending a neurotrauma conference in Toronto were linked in by videoconference as [University of Pennsylvania] physicians presented their most recent technical findings. But the summit ended with no new medical revelations”
“The strong U.S. suspicion that Russia is behind the incidents means that Cuba’s government is no longer considered the likely culprit. Still, officials did not rule out the possibility that the Cuban intelligence services may have offered the Russians some level of cooperation or tacit consent.”
Nevertheless, NBC News said the evidence “is not yet conclusive enough, however, for the U.S. to formally assign blame to Moscow.”
Indeed, on September 11, Heather Nauert, the State Department’s spokesperson, in response to a journalist’s question, said the following: 
- “We have seen . . . a firestorm of reports out there today assigning blame to the Russian Government according to some unnamed U.S. Government officials. I would caution you all to be very skeptical of those officials’ statements right now. As you should be aware, the investigation continues into what has caused. . . – what we have called health attacks on our State Department employees who have been working in Cuba. There is no known cause, no known individual or group believed to be responsible at this time. We are looking into it. Our position has not changed. The investigation is ongoing. We have not assigned any blame and we continue to look into this, so I want to be very clear about this.”
Relevant to the NBC News report is the increase of Cuba-Russia cooperation on various matters in recent years. A noted U.S. expert on Cuba, Professor William LeoGrande, provided the following summary of the recent Cuba-Russia rapprochement:
- In 2000 “when Putin “succeeded Boris Yeltsin as Russian president,” Putin “began rebuilding Russia’s global influence by repairing relations with traditional allies.” The first step was “Putin’s 2000 trip to Havana, which resulted in expanded trade deals. . . .”
- “Raul Castro in 2009 visited Moscow during which the two governments signed 33 cooperative agreements, including $354 million in credits and aid for Havana.“
- In July 2014, Putin visited the island again and agreed to forgive 90 percent of Cuba’s $32 billion in Soviet-era debt, with the remainder to be retired through debt-equity swaps linked to Russian investments.
- When Raul Castro returned to Moscow in 2015, Russia had signed agreements to invest in airport construction, the development of the Mariel port and metallurgy and oil exploration, and had also agreed to lend Cuba 1.2 billion euros—about $1.36 billion at the time—to develop thermal energy plants.”
- In September 2016, Russia announced a new package of commercial agreements in which it will finance $4 billion in development projects focusing on energy and infrastructure, and Cuba will begin exporting pharmaceuticals to Russia.
According to LeoGrande, “Both Havana and Moscow refer to their relationship as a ‘strategic partnership’ that has diplomatic and military components. Diplomatically, Cuba supports Moscow’s positions on Ukraine, Syria and NATO expansion. Militarily, Russia is refurbishing and replacing Cuba’s aging Soviet-era armaments. Russian naval vessels visit Cuban ports, and Russia reportedly wants to establish a new military base on the island.”
