Under Trump we've essentially annihilated them. Don't get your question.
Except for the thousands held in Kurd-run prison camps. The ones who will be back in action shortly. And if they start re-establishing their caliphate? Who stops them?
They started with less than a few hundred and now there are 10,000 in captivity. 10,000 is not “essentially annihilated”. That’s not counting the thousands which are actively fighting in small groups in places like Libya. They could reconstitute in a heartbeat left alone.
