I said that concessions will work no better with ISIS than they will with Nazis and Communists. Both the Nazis and the Communists were revolutionary movements convinced that the world was going their way. When they got concessions, they became emboldened; the only way to be left alone by them was to challenge and defeat them.

Concessions work with people who have "moderate" (asking for more rights or territorial independence) goals. People who are interested in a global caliphate may leave you in peace for a few years if you withdraw from the war (maybe), but they'll be back eventually.
