Here is the thing that both sides on these forums don't understand. It doesn't matter who we elected, we get involved in international conflicts. Why?
Perhaps if people on this forum saw what our National Intelligence knows and studied the real dynamics in this world, we might have a different view.
Maybe it isn't that Bush, Obama, Trump, etc. are war mongers, maybe it is that there is just real sh1t out there that requires our involvement for the betterment of our people.
That being said, when we try to "occupy" and "rebuild" nations, that becomes the problem. Both Afghanistan and Iraq started out looking very good with minimal deaths and money spent. It was the rebuild of both nations, especially ~2-3 years into it, that things started to get rough.
I do wonder about Iraq sometimes. Iraq might be more successful of an operation than we often talk about. Iraq still seems to have the government they elected in control and things are quiet out of that nation. Perhaps that is a success?
