“Attacks” in quotes because despite the hyperventilating news coverage, there’s been no hard evidence that the mystery ailments besetting US diplomats there are the result of deliberate attacks. A far more accurate description of the story would be the Cuban mystery.
Could the symptoms conceivably be the result of deliberate attacks? Of course. But it’s important to stress that such attacks really don’t serve the interests of the Cuban government, which has a lot to profit by improving relations with the USA and so restoring the tourist economy that was disrupted decades ago when US/Cuban relations swirled down the toilet after the Cuban Revolution.
If the attacks are deliberate, the most likely culprit would be rogue elements in the Cuban government’s security apparatus, of which there’s plenty of room for, given that the island is run by a large and intrusive surveillance state. A plausible guess would be hardcore types that are worried about Raul Castro’s desire to have Cuba depart from Fidel’s orthodoxy in favor of a more Vietnamese or Chinese inspired model. But the key word here is guess. At the present time, this is just a guess, nothing more.
Another guess would be some sort of mysterious disease which is causing those symptoms. If that’s the case, Cubans have doubtless also fallen victim to it, so the Cuban government (which runs the health-care system) is aware of the disease and has chosen to conceal evidence of it (most likely because they are worried about its impact on the tourist trade should it be officially acknowledged). This is also just a guess, of course.
However, the second guess seems more plausible to me. That story above hints at (just hints at, mind you, read it fully and you’ll see that the correlations between the symptoms of tourists and those of diplomats have not been well-confirmed) tourists falling victim to the same ailments. What plausible reason would Cuba have for deliberately targeting tourists, particularly given how important tourism is to their economy? A disease makes much more sense.
Earlier I mentioned hardliners and interests being served. The USA also has its hardliners with interests, and I will close by pointing out that trying to paint the ailments as the result of attacks deliberately being carried out by the Cuban government serves their interests perfectly.
