I think what has trashed the Venezuelan regime is that it is a criminal regime, not so much because of the communism it placed onto the people, there are a few aspects of all of this. Communist regimes, really any regime with Venezuela's wealth should survive.
Also, if one says, they asked for it, how about if they start pointing missiles at the US? What if they start fomenting revolution across the region? What if they flood other countries and ours is included, with refugees? We have 260,000 and no, we are not going to turn them back, it won't happen.
What if they sell MANPADS to Terrorists. They do in fact, have those. Man Portable Air-Defense Systems?
And all of this doesn't even begin to address drugs coming into the US as well.
I can see where one could say, we don't take care of our own border, so why worry about this other?
