Why are they leaving home?

Two days ago (I didn't manage to post before, freeroller.net was down when I tried), the departure of GI's for the gulf struck me. The weapons inspector say their work is far from finished, and they have not shown evidence yet. So why send people now? Is it urging? Has the security council more facts than two months ago to take the opportunity to slaughter Iraqi civilians? In North Korea they say they have the nuclear weapon, that they want more nuclear weapon and they are going to get more... but they've got no OIL of course, the Holy Grail of America, the thing that justifies 'collateral dammages' and starvation.
