Thus far the inspections haven't yeilded much, or even deterred Hussien from his pursuit of WMD .
I see it like this we really only have two choices:
1 Permanent inspections, with our military deployed to the region for decades, pissing off the Saudi people who resent our presence and taxing our economy . The inspections would have to be indefinite, as soon as the UN and US leave, he would be back to his old tricks.
2 Finish the war that has been going on for too long and get the bulk of our forces out of there . Yes there will be bloodshed, but it will be brief and it will mean much less bloodshed in the future. Yes we will need civil affairs personel in country to stabilize and rebuild. But again this is much less costly than option 1 .
In my opinion option #2 will yield the most happiness, for us, the Iraqis and the Saudis .
