According to Fabián Escalante, a retired chief of Cuban counterintelligence, the United States made 638 attempts to assassinate Fidel Castro, employing a bevy of bizarre contraptions such as an exploding cigar, a poisoned diving suit, and a booby-trapped conch.
Your common sense exists for a reason. Use it.
"Some people have claimed that the CIA plotted to assassinate Fidel Castro using an exploding cigar. However, there is no evidence that this was ever seriously proposed."
While I don't know much about this Fabián Escalante, I'm assuming that as a chief of Cuban counterintelligence, if there was evidence of this plot against Castro, he would have had access to it. This makes him at least somewhat reputable a source. Of course, he also could've been lying to make the US look bad, but if there's any indication that he was lying, it's not addressed in the Fact on this page. Personally, I'm not sure whether he was lying or not, but I just wanted to bring this up because the two Facts don't totally line up.
I apologize for the duplication, however.
