So in other words, Obama is such a shitty negotiator, or he didn't want any US troops in Iraq, and it all fell apart.
Saying "it was Bush's agreement!!!" is meaningless as it was well known by Obama when he took office that this would be an issue he would have to work to resolve. Obama made a choice, and bragged about his choice, which was disastrous.
FACT: President Obama kept his promise to end the war in Iraq. Romney called the decision to bring our troops home “tragic.”
You think Obama was gonna negotiate to keep troops there? When he rightfully opposed that war and accurately said what the cause of the Iraq war would be? That agreement was signed by Bush and it's his responsibility completely. His legacy will be war, terrorism and ISIS.
