By late 2005 dumbo had lost traction. 66% of Americans, compared to 26%, think the Iraq invasion was a dumb ass move. Jeb put his foot in it, and I hope he can't get out of it.
The latest gallup figures on Iraq have 40% of the public still supporting the move to remove Saddam and only 58% against. When you ask soldiers who actively served in Iraq or were involved in the initial invasion, the majority are proud of their service and proud that they removed Saddam. They also believe George Bush was a better commander in chief than Obama and the majority vote Republican. The American civilian will change their support to majority once the wind is blowing in the right direction.
Most Americans after World War I thought American intervention had been a mistake, but by World War II, most thought it had been the right thing and continue to think so today. Most Americans at the end of the Korean War thought it had been a mistake, but not today. The American civilian feelings on these things do sometimes change over time.
