US & Britain armed and trained Kurdish militias, supported them with airstrikes and special forces, and destroyed all the overt parts of ISIS in the Raqqa campaign (2017) among others. That ended the Syrian phase of that war.
Similarly the US backed up Kurdish and Shiite forces in the extermination of ISIS in the Mosul campaign (2017).

I was paying attention, Eurotrash. My buddies and I were running thermites through the same American equipment that was now being turned against us.
