Sen. Michael Bennet:

Well, I never would have taken these troops out.

In the first place, unlike many things in the Middle East that we have done wrong, this was a case where what we were doing was working. We had been there for five years. It was a critical mission to defeat ISIS. We had lost six Americans, which is tragic, but only six Americans.

The Kurds lost 10,000 Kurds in the same actions that we were taking. And we had managed to deal with ISIS, which is not the same thing as finishing or ending ISIS.

And, today, the president's put us in a position where we're not going to have the opportunity to deal with ISIS if they reemerge. And Syria, Russia, and Iran, and Assad are splitting up the region.
