ISIS strikes back after Assad's fall

ISIS strikes back after Assad's fall

Force in Play

Power vacuum in Syria reignites conflict with Islamic State

December 30th, 2025: CENTCOM Announces 25 ISIS Operatives Killed or Captured

Overview

A lone ISIS gunman killed two Iowa National Guardsmen and a civilian interpreter in Palmyra, Syria, on December 13, 2025—the first American combat deaths since Bashar al-Assad fled the country a year earlier. Defense Secretary Pete Hegseth responded with Operation Hawkeye Strike.

On December 19, F-15s, A-10s, Apache helicopters, and HIMARS artillery struck 70 ISIS targets across central Syria with over 100 precision munitions. Jordan sent fighter jets, and Trump called it vengeance. U.S. forces conducted 11 additional raids between December 20 and 29, killing or capturing 25 ISIS operatives and destroying four weapons caches.

Assad's collapse created the power vacuum ISIS exploited, staging 660 attacks during 2024. By December, after early-2025 quiet, ISIS escalated dramatically—ambushing American forces, bombing mosques to stoke sectarian rage, and killing eight in a December 26 Homs mosque attack, claimed by a new Sunni extremist group. With 9,000 ISIS fighters in Kurdish prisons and 40,000 relatives in desert camps, 900 U.S. troops are all that stands between order and chaos.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

January 16, 2019

January 2019 Manbij Bombing

An ISIS suicide bomber killed four Americans—two soldiers, a Defense Department civilian, and a contractor—plus 15 others in Manbij, Syria. The attack came weeks after Trump announced withdrawal of all U.S. forces, demonstrating ISIS's enduring capability despite losing most territorial control. It was the deadliest attack on U.S. forces in Syria since operations began.

Then

Trump delayed but didn't cancel the withdrawal; forces drew down from 2,500 to 900.

Now

ISIS lost its final territory two months later but proved it could strike even in defeat.

Why this matters now

The Palmyra attack mirrors Manbij's timing—Americans killed during political transition—and validates fears that reduced presence invites ISIS resurgence.

December 2011 - June 2014

Iraq 2011 U.S. Withdrawal and ISIS Rise

Obama withdrew all U.S. troops from Iraq in 2011, declaring the mission accomplished. Iraqi security forces, without American support, crumbled under sectarian pressure. Al-Qaeda in Iraq—barely alive in 2011—rebranded as ISIS, exploited Syria's civil war, then stormed back into Iraq. By June 2014, ISIS controlled Mosul and declared a caliphate spanning Iraq and Syria.

Then

ISIS seized territory the size of Britain, holding it until 2017-2019.

Now

The U.S. returned in 2014 with Operation Inherent Resolve, a mission still running 11 years later.

Why this matters now

The withdrawal-resurgence pattern haunts Syria policy: pull out too soon and ISIS returns stronger, as CENTCOM's two-year regeneration warning suggests.

September 2014 - Ongoing

Operation Inherent Resolve (2014-Present)

After ISIS seized vast territory in Iraq and Syria, Obama launched a coalition campaign in September 2014. Using airstrikes, special forces, and local partners like the SDF, the U.S. slowly squeezed ISIS's caliphate. By March 2019, ISIS lost its final stronghold at Baghuz. But the mission never ended—900 troops remain in Syria conducting counter-ISIS operations, exactly what they were doing when the Palmyra attack hit.

Then

Coalition liberated 100% of ISIS's territorial caliphate between 2014-2019.

Now

ISIS reverted to insurgency, attacking 660 times in Syria during 2024 alone.

Why this matters now

Operation Hawkeye Strike is the latest chapter in an 11-year war that was supposed to end in 2019, proving ISIS containment requires permanent pressure.
