We've seen it, us who live outside of America and have had the pleasure of being invaded. Must be nice to use everyone else's land as battlefields and never having to fight one at home, and ignoring the atrocities and fascism committed by your armies on foreign soil.
WWI and WW2 were absolutely necessary actions to contain others aggression. The Korean war is the only reason that the entirety of Korea isn't under an insane dictatorship. Afghanistan attacked the US (stupidly enough) Iraq v1 was to contain a war of aggression.
Vietnam and Iraq v2 were wrong.
and fascism committed by your armies on foreign soil.
When you send in your cia to round up citizens of foreign nations and execute/torture them, and fund death squads that disappear people without due process, what do you call that but fascism?
