Who do you think is responsible for our failure in Iraq?

BHO owns the fall of Iraq! Senior Military Leaders warned him to leave a Force In Place . . . 10-15K soldiers. Champaign Promises won out and he had EVERYONE withdraw . . . the resulting power vacuum sucked in ISIS!
No more complicated than that . . . Leave it to a Liberal Democrat to "suck Victory into the jaws of Defeat"!
What of the countless deaths of US Service members? Was it all for naught . . . seems so, BHO! PS: GWB had NOTHING to do with this, O!

Current POTUS. For him it was the "bad" war, now he is sending us there again.

well, it seems we won, we had it stabilized. That would be called a success even by stupid people. There was a failure to keep it stabilized by completely pulling out too soon. Obama was wrong, he admitted it when he decided NOT to completely pull out of Afghanistan. That is the BEST statement of a mistake a person could ever make. If he thought he was right in Iraq, he would have done the same thing.

It's a multi-level failure. To blame it on one would be senseless. I think it boils down to what was the bane of the Vietnam War - the politician, not the eyes on the ground, decide what should be done. We throw in the 24 hour news agencies who analyze everything at their specified biases - the general public does not know what the unfettered truth is.

The govnernment itself uses its DIME - Diplomacy, Intelligence, Military, and Economics to try to work with other governments, both big and small, friend or foe. It's those high-level decisions which determine what our military is doing for the next 10 years...

Depends on what you mean by failure, there were lots of failures in regards to Iraq. There are too many to point out, but I'll list a few for you. 1) stand up and arming of Insurgent groups - the push (race) for Baghdad meant that we bypassed and left numerous weapon caches unguarded which insurgent groups later used to arm themselves - Rumsfeld's fault. 2) growing numbers of insurgent groups (such as the 1920s Revolutionary Brigade) which happened due to our elimination of jobs (primarily military and primarily Bath Party members) which only served to piss people off and drive them into the open arms of insurgent groups - Again Rumsfeld's fault. 3) Failure to listen to reason - Rumsfeld asked GEN Shinseki what was need on the ground, the response was 150,000 more troops. After a series of head-buttings, Rumsfeld took that as the last straw and demanded that Shinseki Retire or he would be fired. After Shinseki retired, no one would step up to the position, so Rumsfeld called upon GEN Schoomaker to come out of retirement to take the position. Schoomaker's first act was to ask for 150,000 more troops in Iraq. Again Rumsfeld's fault for not listening to experience. (Each of those three are definitely directly Rumsfeld's fault, but since W stood by him, and as Commander in Chief, Bush was ultimately responsible.) 4) Failure to withdraw without a secure area - premature withdraw from Iraq without ensuring that Iraqi forces could maintain security opened up a vaccum that allowed ISIS to take root and capture vast areas of Iraq. This one has the blame completely resting on Obama's shoulders.

Scooter Libby.

We won the war and lost the peace. When DOD turned the country over to the State Department it was over. They stood down the Iraqi army and dumped the leadership. They called it de basification. Like purging Germany after WW2 of all Nazis. Now a lot of ISSI leaders are x-Iraqi officers including some generals.

The President is responsible for everything America does or fails to do... Leadership 101

I'm sure given enough time, imagination, ignoring certain facts and exaggerating some meaningless conversation like this administration, I could walk this back and blame FDR and maybe even blame President Lincoln. That being said the withdrawal of all our forces under this administration just to have some political bragging Rights for a re-election campaign, I have to say it's Obama fault. Having troops would mean having advanced intelligence. It's like the cop on the beat, he/she hears things on the street

WTF?? We're seeing it as down 3-2 in the bottom of the third.
Granted this is kinda embarrassing because we knew how to do this, but sometimes you start the wrong pitcher. What can ya do?
