When has int'l law (or The Hague) been a factor to how the US conducts business?
Why should it be a factor now?
I'm mostly pissed that European nations simply obey
It doesn't hurt that they're our allies(1) and that we have enough conventional firepower to level their cities AND much of the countryside as well, at least of any one nation(2).
They "simply obey"'ed when America went to war with Iraq, with either Nato or the EU-portion of the UN bending over backwards to support our hawk lobby (I can't remember which agency was involved.) Of course, France, Germany and Russia opposed our motion for war. It kinda sucks they were just being dicks about their arms sales to Iraq -with the 4th largest military in the world, Iraq was pretty profitable customer-, and not actually opposing the war on conscientious grounds.
That America is occasionally allowed to play 'puppetmaster' with foreign states is something of a testament to the sheer psychological power wielded by our government. It's also nothing new.
