Every country that loses a war and still manages to survive intact has a tendency to blame the defeat on treachery. The Argentinians blamed the Americans for supplying the English with intelligence during the Falklands, the Germans blamed the Jews for their loss in WWI and the Arabs have blamed the US for every defeat they suffered against Israel.

Clausewicz tells us that war is just an extension of diplomacy, and by that criterion the Vietnam war was a draw. We may have not been able to save the South Vietnamese government we supported, but our primary mission (the reason I was given for having to go there)--to prevent the states of Asia from falling like dominoes to the communists--was a resounding success.

Yes, this Iraq war has a lot in common with the Vietnam experience, and for many of the same reasons.
