Anyone paying attention knows the US won't take "yes" for an answer; like all other democracies, they aren't agreement capable. Showing weakness of any kind is just chum in the water to these sharks. Also, if they really have a bug up their ass about ya, they're just gonna go terminator on your ass and will not stop ever until you are dead. As such there is no rational reason for anyone to ever comply with US demands internationally. Make them pay for every inch with blood.
