Chicanery, or bad water?

Two Cuban diplomats have been expelled after a number of U.S. diplomatic personnel had to return to the U.S. with unspecified maladies.  Now perhaps this is true chicanery along the lines of what was consistent in Moscow during the Cold War (or is now?), but I have to wonder if what's really going on is they're going outside the embassy for food and forget warnings not to eat raw fruits and vegetables, and not to take ice with one's drink.


Hopefully our State Department is not quite that stupid, but after the recent spate of leaks, I'm not quite so sure.  At any rate, it strikes me that if State is correct in their assessment, then Cuba's not exactly the friendly nation Mr. Obama assured us it would be.


Update: the problem appears to be an "acoustic attack" with sound beyond the audible range.   Given Cuba's extremely tight control over their economy, it's hard to believe anyone but the "friendly" Cuban government and the Castros are behind this.  Once again, heckuva job, Barry.
