Then maybe I am mistaking you for someone else that shares your viewpoint in regards to Iraq's current array of weapons and Saddam being in power as the result of the US.
Obviously there is no clear-cut answer, and neither you nor I are at the top rung of either of our nations. Therefore we aren't privy to the information they have and/or the decisions they will make in post-war Iraq *IF* war happens.
Either way, the region is unstable as is. Saddam not disarming and openly stating he won't disarm, and also openly defying the UN in regards to disarmament is creating an even more unstable future and bleak outlook in the Middle East.
If he were to disarm and keep only the weapons he's allowed to keep, the whole thing would be moot.
He won't, and isn't, and never will... leaving him in power will leave a cloud of uncertainty and questionable stability in that region for years to come.
One thing is for certain though, US personnel have remained in that region since the end of the Gulf War, why would you question what the US would do at the end of this increasingly potential conflict?
