From DailyKOS:

In Vietnam, we suffered 1,864 killed between 1961 and 1965, an average of 373 per year (someone I'm sure can find more precise numbers). In the eight months since Bush launched his war, we have suffered 316 dead, plus an additional 54 allied deaths. And that paints just part of the picture. In the first five years of the Vietnam War, we suffered 7,337 wounded in action, or an average of 1,467 per year. In Iraq, we have suffered at least 1,695 wounded -- meaning we are running higher than casualty rates of those early years of the Vietnam War. Bush has gotten us into a mess he can't fix, and real people are suffering the consequences. And no matter how rosy a picture they may try to paint, fact is, we've got a clusterfuck on our hands.
