Travel Ban on Cuba

There have been 100 million deaths that can be linked to either decisions made my a Communist government or directly by the Communist government. Does this sound like something that we as Christians should support? While Castro is still alive we should not lift the travel ban and trade embargo on Cuba. The article said that money spent on tourism would just be like putting oxygen into the dying Castro regime. Travel to Cuba would send millions of dollars into the Castro regime, just giving him fuel to thrive on. The article also talks about how if Cuban exiles were able to return to the island whenever they wanted, it would abuse their refugee privilege. Lifting the travel ban would be unsafe because the president would only be able to step in and do something about it if there were an "armed conflict or armed danger" arises. I think that if the travel ban is lifted it will send out a message to everyone in the world that we support the Castro regime, therefore saying that we support communism.
