I dunno.
It looks like to me that there really is no Iraq.
Give the Kurds a state. Let the Saudis control Anbar, and the Iranians control the east.
Of course, they will immediately fight over borders,,,,,,

Well, if we had been giving that training and weaponry to the kurds for all this time, we might have gotten something out of it.

To be honest, with the benefit of hindsight, I don't think Biden's plan (which I supported at the time) wouldn't have prevented much of where Iraq and most of region is facing with ISIS

But, had we accepted Biden's plan maybe there wouldn't have been an ISIS.  Who can say?

I agree with Goose here and would even go one step further to suggest there really never was an 'Iraq' in the first place.  It was a chunk of real estate occupied by three Islamic sects held together by Saddam Hussein.

I kind of look at it as if we're going to play "we shoulda", the teachable moment was that we should have never gone to Iraq in the first place. Does that mean we wouldn't have seen an increase in radical Islam in the last 14 years, but I do think the entire region would be more stable. 
 

I agree. Invading Iraq was the biggest foreign policy disaster of our time. Perhaps worse than Vietnam.
I would suggest that ISIS is one of the outcomes of this debacle.
The only beneficiary I can see is Iran.

The question I have is, where now?
Withdraw completely, partition Iraq, something else?

We have a great deal of culpability for the suffering that is occurring in the region.
Can we do anything productive now, or is our involvement just going to make it worse?

BOTH were huge mistakes, however, IMHO I believe the long lasting effects of the Iraq invasion and removal of Sadaam will be much worse than Vietnam by a long shot.
