During this election campaign, there are some who have tried to label opposition to the Iraq war as "not supporting our troops," but I think that generally people haven't bought that argument. Still, I get campaign literature every day that tries that, usually from non-veteran Republicans trying to accuse Democratic military veteran candidates of failing to support the troops.
Yes, Americans have been very supportive of returning soldiers, and I'm glad of that. It's the politicians that make the decision to fight, not the soldiers. Many of us anti-war veterans learned that the hard way.
