The Cuban experience is no different than the WT record in countries with dictatorial governments. I am pretty sure sooner or later the JWs and the Castro Government were going to clash, but certainly our defiant behavior accelerated that clash. I don't know if you have any proof of actions taken by the WT during those 30 long years to help the brothers in Cuba, I was a little bit closer to the situation and I don't know of any.
What I saw was a hard line approach, one that I can assure you was highly prejudicial like the instruction to open without permission all the KHs. What came after that fiasco was a nightmare and the start of a new wave of persecution.
By the way, the little bit of relief that the Brothers got from time to time, came from the influence of an Aunt of Castro who was a witness and kept pestering him about what was going on.
