it's simply suspicious how badly people are willing to twist historical fact to let BHO and him monumental incompetence off the hook.
Much of ISIS, and certainly the bulk of it's military leadership, are ex-Iraqi army Sunis.
When we disbanded the army they had military skills, access to weapons, no employment and were stuck in the middle of an unstable sectarian nightmare.
They went where they could use their skills and support themselves.
There were lots of other mistakes made by W and O, but if you can't see this simple fact then your judgment is what is suspect.
