So you support an orderly withdrawl but see no obligation to support those in Iraq who have helped us? You think it is ethical to go in, stir things up, ask the population for help in killing the bad guys, then just leave them at the mercy of those same barbaric monsters?
I think it is ethical to go in, free them from a tyrant, ask them to get their shit together, give them a little time to do that, then withdraw when then fail to do so and the alternative is an open-ended engagement that could last decades.
As for the "same barbaric monsters", it's not. The monsters we fought going in were Saddam's goons. Now there are multiple gangs of monsters (including gangs drawn from amongst those we freed, like the Badr Brigade and the Mahdi Army--both Shia militias, yet somehow part of the problem.
Besides, you make it sound like we can
definitely save them...that's not clear. We can definitely prolong the insurgency, but there is no good evidence that we can end it. If we leave in ten years--that's 10 years of a prolonged insurgency--the violence that erupts when we leave can stiill be just as bad or worse as it would be if we left tomorrow. In that case, we merely dragged the suffering out and not ameliorated it. Sometime you just have to tear the bandage off the scab quickly, not peel it off slowly. It may hurt either way, but a short sharp pain can be better than a longer, drawn out one.
There is no easy military solution in Iraq. There is a political one...but it's not clear that our presence helps reach it. In light of the uncertain benefit we provide to the Iraqis, it's better to consider the costs and benefits to ourselves and base our decision on that. As I said above, that's also murky, but not as murky as the path to peace in Iraq. I am about as hopeful that the Palestinians will achieve democracy, as I am the Iraqis.
My best guess for a "fix" in Iraq, honestly, would be to transition control over to a U.N. peacekeeping force under non-U.S. control; preferably with a relatively large contingent of soldiers from Middle Eastern nations. They's likely be viewed as more of an honest broker than the U.S. is, even though many of our troops would have to sytay yunder a U.N. banner. (My real best guess for how to win the peace for the Iraqis is to slaughter everyone who might possibly pose a risk to stability there, and letting collateral damage be damned while doing so...that would set us up for a century of terrorist attacks on us, from the ranks of a hugely swelled and militant al Qaeda , but I bet we could end the insurgency
in Iraq within a year.)
