I mean...we've been fucking the world up since Korea and Vietnam. Arguably also WW1 (2 we sort of had an excuse because of Japan). And South America before that.
In theory it is the idea that we minimize harm to the heartland by engaging threats/"threats" before they burn down the white house again (mad props to Canada).
But nah. This is just the republicans continuing to be fucking morons. Like when perry (?) campaigned on killing the DOEnergy, got appointed as head, and realized that there were nukes next to all that clean coal.
