If we had redeployed when Murtha wanted to ... we would still have had planes to bomb Zarqawi. But Steven Green might have left the country in January instead of doing what it looks like he did in March. (Which is greater, anyway? The loss to America from the rape and murder of that girl and her relatives or the gain from killing Zarqawi?)
We can play Karl Rove's time machine game too. We
really should have pulled out of Iraq way before Murtha said to. We should have pulled out back when Bush's people said we could. They said we could pull out in
"weeks, not months." It looks like we are going to have to hurry to make that schedule.
If we had pulled out early like Bush and his buddies said we could, think how much better things would have been. There would have been no Abu Ghraib for one thing. About 2,000 fewer American soldiers would have died. I guess the downside is that there might have been sectarian violence.
Take a time machine and go back to every single moment of the Bush presidency. One thing will be clear. You will be happier and happier as you go backward in time. Every month of the Bush presidency finds America better off than every month that followed it. Keep going backward and you reach Clinton. I recommend relaxing there for a while before returning to the present.
