You seem earnest, could I recommend a movie to you. It deals with the socialist nation of East Germany, been a while since I watched it, so I'm fairly sure it is subtitled. Written by and acted by Germans around actual events (as much as is possible in a 2 hour film). It's called The Lives of Others. Another would be Der Tunnel or The Tunnel. Another great documentary about our neighbor to the south is Cartel Land.
We didn't really invade Nicaragua- it was more a case of financial support for resistance fighters against the Sandanistas. I mentioned one refugee friend, I have others that I have to believe were murdered, because I lost contact with them during the revolution. Others I was able to reconnect with.
I have really been fortunate to have a very unique life where I have worked i burnsn DC, in fact over the years have worked in 42 states. I speak several languages, some more fluently than others. I have traveled extensively and visited socialist countries. I've had security clearances and yet right now I drive a truck over the road (like I said- unique). I have met literally thousands of people over the years and truly have an interest in their stories, so I ask a lot of questions, and I write a lot of it down. I've nearly died too many times, saved several lives along the way, and always asked questions then shut up and listened.
It has been pretty consistent, whether a Russian, Cuban, Nicaraguan, Chilean, German, Korean, Vietnamese, Cambodian, Venezuelan or other refugee. We don't appreciate what we have in the US enough and socialism and it's variants are fundamentally evil. The ruling class always gets richer and the people suffer. I saw the last violent US socialist revolution first hand and it wasn't sticking flowers in gun barrels. Everyone knows 4 students got killed at Kent State, how many got bayoneted? You can find it if you dig a little. I know one of the guys, and he told me a lot about the inside of the "movement". Believe me it is evil to the core. Bernie campaign workers are saying if Bernie doesn't get the nomination Milwaukee burns. ??? Really? BUt you know what, happened before, I wouldn't be surprised. If your ideas don't win, destroy. Same as it's always been.
