There is credible evidence--not a certainty, but credible--that South Vietnam could have held out if the U.S. had not cut their military and financial support off, essentially throwing them to the communists.

It's possible this could happen in Iraq too, with us withdrawing, the support cut off and the Baathists and Islamists tearing the country up between them. God knows this is what a lot of people in America seem to have as their goal.

I suppose like the thousands of Vietnamese thrown into internment camps, killed, or driven into the ocean, the annihilation of Iraqis after we give up won't really be "news" any more.

One wonders what South Korea would be like today if we'd given up there.
