Press on
I am not for letting the Iraqis and Kurds do the job. IMO we made a mistake in Afghanistan by relying on the locals.
If we had done the job ourselves, we would probably not be speculating on the whereabouts of OBL and his henchmen.
The stakes are even higher in Iraq. All we need is for the locals to get bogged down and give Saddem a chance to start lobbing gas/bio canisters. Our best course is to fully use our tech superiority to take him out as fast as possible.
