We couldn't solve the Iraqi political problems for them when we had 170,000 troops.

the threat from ISIL that that poses to us, to our allies, to our partners, and the importance that puts on pushing back on them.

I agree that the sectarian violence that had been raging in Iraq at the height of the war was significantly diminished, significantly, by the time that we departed.

I think that things may have been different, but I don't know that we wouldn't be in a similar situation to where we are today.

I think that it is critical that we have a thoughtful regional approach to this problem before we jump in.

I believe so.

It is the political piece and that is critical.

of course we are invested in making sure that it continues as a viable state and doesn't become a breeding ground for terrorists.

we have invested incredible amounts of blood and treasure.

the Iraqi leaders could not get it through their Parliament.

There is no way--the ISIL threat, it is like air in a balloon.
