Is one year enough?

So, did Obama negotiate, or run to get troops out of Iraq after being told no once?  I dunno, let's check:

Despite Difficult Talks, U.S. and Iraq Had Expected Some American Troops to Stay

And for the negotiators who labored all year to avoid that outcome, it represented the triumph of politics over the reality of Iraq’s fragile security’s requiring some troops to stay, a fact everyone had assumed would prevail. But officials also held out hope that after the withdrawal, the two countries could restart negotiations more productively, as two sovereign nations.

A year of negotiations.  They met by teleconference most times.   But it broke down simply because America wanted immunity, and the Iraqi people (not Malaki) didn't want to give it to us.  A year.  How much longer do you need for it to BE a negotiation, or for Dana to notice? 

Dana isn't stupid, nor is she ignorant of facts.  Why would she be so blatantly wrong here?
