Yeah, just like it's easy for people in todays society to say things like:
"I would never have been a slave, I would have told those slavers to kiss my butt"
And:
"I would have never wound up in one of Hitlers camps, or have been under the rule of Pharoah.. I would have taken up arms against them"
That truth is, you would have done both or died right then and there. It's easy to talk when it's not you in the situation.
Also, imho.. The Cuban people need more than weapons to overthrow Castro.. They need confidence and leadership.
Two things Castro spends alot of time and money psyching them out of. He even has a museum dedicated to failed espionage attempts.
