We left the Vietnamese high and dry. We won the battles and lost the war because of lack of interest back home, along with outright cowardice and traitorism. These people depended on our loyalty and dedication, and we ran, making them pay with their lives.
The difference between them and Iraq is that now, if we leave too soon, we'll pay with our lives, as will Europe.
It was not my intention to compare Vietnam with Iraq. It was just a kind of cyniscm as a reaction of a silly posting from one user here.
