The Islamic State declared its caliphate on June 29, 2014. At one point it controlled a territory larger than Britain, and it attracted 30,000 Muslims from 100 different countries to join it. Unfortunately, few, if any, Islamic State jihadis will take its collapse as a sign that their premises were wrong; they will just go wage jihad somewhere else, which is why Western countries are suicidal to take back the ISIS jihadis who are their citizens.

This collapse is due to President Trump. When Obama left office, it looked as if ISIS was here to stay, and was on the path to legitimization, a la the Palestine Liberation Organization.
