Sanctioned? We don't need no stinkin' endorsement. We took our case to the UN, they voted unanimously to give saddam "one last chance". He blew it, we attacked, as we said we would. We are taking care of the aftermath. We have approached the UN, by multilateral request & they again voted unanimously to assist Iraq. We're still waiting. Some countries have come through (not the ones that had illegal dealings, surprisingly) & some are sitting on their hands, probably waiting for the French (in all their might & glory) to say jump.
Pointless, you say? I'd bet there are several million Iraqi's who would argue that point. I'd also bet that there are some very shaken terrorists who have serious concerns with so many GI's breathing down their necks. No, I think it was a right & just move on our part.
