Reid agreed that it was even worse than Vietnam:

After months of heated rhetoric slamming President Bush’s Iraq policy, the Senate’s top Democrat moved into new terrain by declaring the Iraq war a worse blunder than Vietnam.

“This war is a serious situation. It involves the worst foreign policy mistake in the history of this country,” Sen. Harry Reid, D-Nevada, told CNN’s “Late Edition with Wolf Blitzer.”

“So we should take everything seriously. We find ourselves in a very deep hole and we need to find a way to dig out of it.”

Asked whether he considers it a worse blunder than Vietnam, Reid responded, “Yes.”

There were 58,169 Americans killed for a war that we lost. Millions of civilians killed after we pulled out. I would think that loss would far exceed what we have currently endured, especially when you consider the fact of how costly it’s been for our image. Bin Laden believed he could beat us because the Viet Nam war demonstrated that we were a “paper tiger.”
Reid’s rhetoric is so far over the top that it will come back to haunt him some day.
