It is the same speech..and it still holds true....its just that we have changed...and for the worse....sad...very sad..
I don't think it's the fact we're at war, I think it's the fact that there hasn't been much progress (at least visible progress) in the last three years. Americans can deal with war, but they cannot deal with a war of attrition, holding patterns and occupancy.
In WWII, for example, if we had stopped in France after the Normandy invasion, and sat for three years while negotiating with Germany and trying to set up a provisional government in France, taking a few losses every day, I think the citizens would have said, "screw this, bring them home."
One lesson American presidents should learn is that if you want to keep the citizenry behind you in a war, you have to keep showing progress.
