I thought ISIS was already defeated. And the Russians and Syrians seemed to be doing a pretty good job of doing it without our help. At what point do we pull our troops out of there. A year? 5 years? 10 years?
You thought wrong - ISIS severely beaten, is not defeated, yet.
Completely incorrect. the Russians and Syrians are not battling ISIS, they are merely bolstering the Assad regime of his internal opponents.
