don't even have to back to Bay of Pigs to see US backed wound-up-and-set-loose terrorists like this:

the only surprise here is that the US media is reporting it happened, instead of vanishing it down a black hole while characterizing the cuban government as paranoid for pointing out that terrorists are allowed to fundraise, plan, execute terror campaigns all from the safety of the US with the full knowledge and support of the government.

while the cuban government supplied information to the US government law enforcement about these criminals, the FBI would insist it needed more evidence. the cuban government, taking the US government at face value, infiltrated US based cuban terrorist organizations and supplied reams of evidence with specific crimes linking to specific people. the FBI took the evidence and used it to root out the infiltrators and lock them up in prison, while ignoring the terrorists. the movie the Wasp Network is about this event and the Cuban Five, the heroes of this story who were run through a kangaroo court and convicted with heinous sentences of many decades on bullshit charges.
