If you don't want to be blamed for killing people when you take sides in another country's civil war, stay the **** out of it. The US claimed we had to stop N. Vietnam or else country after country would fall to communism. Did that happen, or have we been doing business with Communist Vietnam for decades?And? Do you assume there would be no bloodbaths if we hadn't been involved? That the U.S. just automatically generates them by its' mere presence? That none of those peoples are to blame for anything? Is there some reason why people who habitually use this as a talking point can never bring themselves to blame, say, the Soviet Union and Ho for Viet Nam, for instance?
I'm very familiar with the civil war started by the railroad lawyer from Illinois for the benefit of his financial swindler Republicans up North. That was key to creating the Republican Party in the first place, destroying the South in order to help themselves to massive handouts. What do you want to know about it?
Was it bloodless like you apparently expect civil wars in other countries to be?
