I am trying to run through different options and try to figure out realistically how this is going to turn out. I don't want to get into biases or emotional posts, or discussion of past errors but I'm just trying to think this through. Where are we going to be in four years. What should we do for our and the world's best interest?
Lets start with the option that we continue the surge and lets figure what success might look like. I know many groups in Iraq hate us being there and see us as occupiers and the current government as our puppet government. I guess we could hope that gradually the insurgent attacks decrease and maybe in three years or so our forces can gradually start to withdraw. Iraq will probably be a volatile place with potential for civil war outbreak. How long would we have to stay to keep peace there - 5 years, more?
If we gradually withdraw, civil war might continue and escalate and consume the entire country. Like many countries they might have this war until a victor emerges or they resolve conflicts. In the chaos it could be a haven for terrorist cells. However, maybe with the American "occupiers" out of the picture Iraq's would be less inflamed and more likely to try and find some resolution to their problems.
Whether we stay and gradually withdraw, the best choice might be if the Saudis, Iran and Pakistan held the Iraqi's development some peace plans. Possibly some federation with sharing of wealth.
I really can't see the realistic outcomes to this situation.
