Eventually we will be out of Iraq, as will be 2 million, or perhaps by then 5 or 10 million Iraqis. The world will watch to see what happens to the refugees created by our invasion.
And when the US fails to admit Iraqi refugees as immigrants, our "friends" around the world will not fail to note. They will be less inclined to support America in conversations or official acts. They will become positively truculent about supporting invasions or civil disorder desired by the US.
Which is probably all for the best. But with a couple of gibbering baboons in our own cockpit, there is no soft landing on our horizon.
