I can’t speak for the rest of the world, but I imagine their general disdain for Americana (despite their embrace of American pop culture) factors in there somewhere.
I don’t think Bush fucked the diplomacy, France et al did. If they’d played with us, bluffed, and multilaterally told Saddam we were going to bomb him into the 8th dimension if he didn’t give up the ghost, we wouldn’t have had a problem getting him to fold. Instead, they all showed early on that they’d put a monkey wrench in UN intervention, and as a result, the US and Britain had to step up to the plate.
I fully believe there would NOT have been a war if France, Germany, and Russia had just played along with our threats of making good on 1441. Instead, they made a selfish power-grab, and we had to carry the slack, lest we look afraid of going to war.
The Osamas of the world love to see America back down from a hard-line stance, because it reinforces their belief that they will not recieve retribution for their actions. Just like us pulling out of Somalia showed him in '93.
