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.

Trump's ISIS Strategy

On the campaign trail, Trump promised to "bomb the shit out of ISIS... They've got to be stopped."

How They Responded: "Trump's ISIS Plan Is Dangerous Fantasy"

"The complexities of tackling ISIS in two countries amid an array of competing parties do not give themselves easily to campaign slogans. Short of accepting far greater destruction to cities as well as amplifying civilian suffering and displacement, it's hard to see how more intense airstrikes would change the military balance overnight."

The Evidence: Trump Was Right

Under Trump's leadership and revised military strategy, ISIS suffered rapid and devastating territorial losses, leading to the complete collapse of its self-declared caliphate.

What Has Surfaced Since Trump Returned

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.

Even Syria Now Fights ISIS Alongside the United States

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 Vindication: Military Success Acknowledged

"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."

"Within minutes of President Donald Trump's inauguration, the White House issued the 'America First Foreign Policy' manifesto stating that 'Defeating ISIS and other radical Islamic terror groups will be our highest priority.' This commitment led to significant changes in military strategy that accelerated the defeat of ISIS."
The Hill Logo The Hill
"The Trump administration's military strategy, including changes to rules of engagement and increased delegation of authority to field commanders, has been instrumental in accelerating the defeat of ISIS. The results speak for themselves, though many in the media have been reluctant to acknowledge this success."

Final 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.
