With all the bunker mentality and the gloom and doom predicted by the WT it is good to remember the Cuban debacle in that field.
As I mentioned before, the WT attitude towards the Castro Government was antagonistic from the beginning. Something that was implemented and backfired big time was trying to use the communist literature against the officials.
There was a booklet from Lenin, the founder of the Soviet Union called "About Religion" and it stated in some portions the need for religious tolerance and freedom. Some of the brothers quoted this source when talking to the police, the results were really, really bad.
Incidentally the Lenin booklet was written before his takeover, like Castro once that he was in power it was a different situation and behavior.
