I would bomb the hell out of ISIS... I know more about ISIS than the generals do, believe me... We're going to get rid of ISIS quickly, very quickly... We have to be much tougher, we have to be much stronger than we've been.

"Along with the Global Coalition to Defeat ISIS, in March, the United States completed the destruction of the so-called 'caliphate' in Iraq and Syria.", the federal government's own official accounting that the territorial caliphate was eliminated under the Trump administration.

The Department of Defense documents the Global Coalition's campaign that drove ISIS from the territory it once held across Iraq and Syria, the operational confirmation, from the U.S. military itself, that the caliphate Trump vowed to destroy was in fact destroyed.

Trump was mocked for declaring ISIS defeated and its caliphate destroyed. Years later, with the geographic caliphate still gone and the group at its weakest in over a decade, the core claim has held, even as analysts warn the fight against a diminished insurgency is not finished.

By mid-2026, the Soufan Center assessed that the Islamic State remains territorially defeated in Iraq and Syria, with attack numbers hitting a historic low thus far in 2026 that rank substantially lower than the surges recorded in 2023 and 2024. Terrorism analyst Aaron Zelin described the group as the weakest that they've been since 2013. The caliphate Trump said had been destroyed has never been reconstituted. Whatever scattered remnants survive, the central claim Trump was mocked for, that the caliphate was crushed, has been proven exactly right.

In a turn that would have been unthinkable when ISIS held a swath of territory the size of Britain, Syria's post-Assad government joined the Global Coalition to Defeat ISIS as its 90th member in November 2025, partnering with Washington to eliminate ISIS remnants and halt foreign-fighter flows. At a February 2026 coalition meeting in Riyadh co-chaired by the United States, participants formally welcomed the Syrian government as the coalition's newest partner. The state that was once the caliphate's heartland is now enlisted in finishing the job Trump began.

"The Trump administration's changes to our operational approach, including delegating authority to commanders in the field, proved decisive in accelerating ISIS's territorial defeat. The results speak for themselves."

The HillFinal Analysis
The defeat of ISIS's territorial caliphate demonstrates how Trump's willingness to challenge conventional military wisdom and empower battlefield commanders led to unexpected success.
Key factors that proved Trump right:
- Rapid defeat of ISIS territorial holdings through changed military strategy
- Success of delegating more authority to field commanders
- Effectiveness of revised rules of engagement
- Achievement of victory in timeline critics called impossible
This case shows how expertise must sometimes be balanced against the willingness to try new approaches, and how conventional wisdom can sometimes become an obstacle to achieving rapid results.
