Actually he can.
Obama cut and run to appease his far left base for the 2012 elections.
He did not try an negotiate, just left (also left a lot of military assets in Iraq).
Although it really started when he drew a line in the sand, and then did it again, and then did it again.
Obama has blundered the middle east. Then his stance with Putin (the new world leader) really showed the weakness in the US.
This happened one other time in History and that was when Carter was soft on foreign policy.
Then again if you want to pass the buck you can go way back in history including when the British occupied Iraq in the early 1900's.
However to the far left the history of Iraq did not start until 2003.
Obama funding & arming very questionable rebel groups in Syria has led to this current chaos. It was a blunder for sure. ISIL is the awful Blow Back on that. He should have kept us out of the Syrian War. Assad, Russia, and Iran would have crushed ISIL if we had stayed out of it. We gave them new life. So Obama is somewhat responsible for this current mess, but it can't be all on him.
He did not support the Iraq War.
Exactly! See my earlier comments on that.
Obama was more about appeasing his far left base over being a leader.
He has been soft in one to many areas.
Russia was arming the Syrian government, Russia has armed Iran and now they are trying to muscle their way in to arm Iraq.
Pretty soon it will go back to they way it was in the 70's with Russia having the controlling interest in the region.
Iran was not doing much against ISIS, nor was Russia, nor was Iraq.
The problem is the Iraqi army did not have the confidence it needed to take out ISIS. That confidence could have some in the support of 20,000+ troops stationed in Iraq before Obama cut and run so he have the far left base behind him.
