Joint US-Jordan Airstrikes Target ISIS in Syria: A Coordinated Blow Against Resurgent Terrorism
In a swift and decisive response to a deadly terrorist attack, the United States and Jordan launched coordinated airstrikes on December 28, 2025, targeting more than 70 Islamic State (ISIS) positions across Syria. The operation, described by U.S. officials as a “precision campaign,” struck command centers, training facilities, weapons depots, and operational hubs in multiple provinces, including Deir ez-Zor, Hasakah, and Raqqa. Coming just days after an ISIS-claimed suicide bombing in Amman that killed 12 Jordanian civilians and wounded dozens, the strikes underscore a renewed commitment by Washington and its key Arab ally to degrade the group’s lingering capabilities in the region.
The joint mission highlights the enduring partnership between the U.S. and Jordan in counterterrorism efforts, even as American focus shifts toward great-power competition. While ISIS no longer controls vast territory as it did during its 2014-2019 “caliphate,” intelligence assessments warn of a slow resurgence, with sleeper cells exploiting Syria’s ongoing chaos amid the protracted civil war.
The Trigger: Deadly Attack in Amman
The catalyst for the strikes was a devastating suicide bombing on December 25, 2025, at a popular Christmas market in downtown Amman. The attacker, identified as a Syrian national with ties to ISIS-Khorasan networks, detonated an explosive vest amid holiday crowds, killing 12 people—including three children—and injuring over 40. Jordanian authorities quickly linked the perpetrator to ISIS operatives in eastern Syria, prompting King Abdullah II to vow an “unrelenting response.”
U.S. President Donald Trump condemned the attack as “barbaric” and pledged full support to Jordan, a steadfast ally hosting American troops and playing a critical role in regional stability. Within 72 hours, joint planning culminated in the airstrikes, executed primarily by U.S. F-15E Strike Eagles and Jordanian F-16s operating from bases in Jordan and the Gulf.
Pentagon spokespersons confirmed that over 100 precision-guided munitions were employed, with initial battle damage assessments indicating severe disruption to ISIS logistics and leadership networks. No civilian casualties were reported, thanks to extensive intelligence preparation.
Scope of the Operation: Targeting a Resurgent Threat
The strikes hit more than 70 sites across Syria’s eastern and central regions, areas where ISIS remnants have regrouped since the territorial defeat of the caliphate in 2019. Key targets included:
- Underground command posts in Deir ez-Zor used for planning external attacks
- Training camps in the Syrian Desert (Badiya) where new recruits were being indoctrinated
- Weapons caches containing rockets, IED components, and drones
- Financial hubs facilitating extortion and smuggling
Jordanian aircraft focused on border-adjacent targets, while U.S. forces provided the bulk of firepower and real-time intelligence via drones and satellites. The operation marked one of the largest single-day airstrike campaigns against ISIS since 2020.
Military analysts note that ISIS has adapted to its post-caliphate reality, operating in small, decentralized cells that blend into civilian populations. Recent months saw an uptick in attacks: assassinations of Syrian regime officials, ambushes on Russian and Iranian-backed forces, and plots against Western targets. The Amman bombing represented the group’s boldest external operation in years, signaling ambition beyond Syria’s borders.
Historical Context: A Long War Against ISIS
The Islamic State’s rise in 2014 shocked the world, as it seized vast swaths of Iraq and Syria, declaring a caliphate and committing atrocities that drew a U.S.-led coalition into the fray. Operation Inherent Resolve, launched that year, eventually liberated all territory by 2019 through a combination of airstrikes, special forces, and support for local partners like the Syrian Democratic Forces (SDF).
Yet, ISIS never fully vanished. Thousands of fighters went underground, with detention camps in northeast Syria holding tens of thousands of suspected members and families. Breakouts, such as the 2022 Hasakah prison attack, demonstrated ongoing threats.
Jordan has been a frontline state in this fight, suffering attacks like the 2016 border assault and hosting U.S. troops at bases like Muwaffaq Salti. Amman’s intelligence services are renowned for penetrating jihadist networks, making the kingdom a vital partner.
The latest strikes come amid broader regional instability: Syria’s civil war grinds on, with Bashar al-Assad’s regime weakened, Iranian militias entrenched, and Turkish forces controlling northern enclaves. This vacuum allows ISIS to exploit seams.
International Reactions: Support and Caution
The operation drew widespread international support. European nations, still haunted by 2015-2016 ISIS-inspired attacks, praised the action. The United Kingdom and France issued statements endorsing “targeted measures to prevent terrorism.”
Arab states were similarly supportive. Saudi Arabia and the UAE, long wary of Islamist extremism, welcomed the strikes. Iraq, which shares ISIS concerns, coordinated quietly to ensure no spillover.
Russia and Iran, backing Assad, issued cautious statements. Moscow called for “coordination with Damascus,” while Tehran warned against “violations of Syrian sovereignty”—rhetoric consistent with their opposition to U.S. presence in Syria.
The SDF, controlling much of the targeted areas, reportedly provided ground intelligence, reinforcing their role as America’s primary partner against ISIS remnants.
On social media, reactions varied: jubilation in Jordanian circles, calls for sustained pressure from counterterrorism experts, and skepticism from anti-intervention voices questioning long-term efficacy.
Strategic Implications: Can ISIS Be Kept Down?
Experts debate whether such strikes can permanently degrade ISIS. While tactical successes are clear—disrupting plots and eliminating leaders—the group’s ideology persists, fueled by governance failures in Iraq and Syria.
The U.S. maintains around 900 troops in eastern Syria, primarily to prevent resurgence and secure oil fields. Jordan hosts additional forces. Yet, with Washington pivoting resources toward China and Russia, sustaining high-tempo operations is challenging.
Some analysts argue for broader approaches: stabilizing detention camps, repatriating foreign fighters, and supporting local governance to deny ISIS recruitment pools.
The joint U.S.-Jordan operation demonstrates that, when directly threatened, coalitions can still mobilize effectively. It sends a clear message: despite territorial defeat, ISIS attacks will invite overwhelming response.
Looking Ahead: Vigilance in a Volatile Region
As battle damage assessments continue into December 29, attention turns to potential retaliation. Security alerts rose across the Middle East and Europe, with fears of lone-wolf or inspired attacks during New Year celebrations.
For Jordan, the strikes bolster national resolve after the Amman tragedy. For the U.S., they reaffirm commitments to allies amid domestic debates over foreign engagements.
The fight against ISIS enters its second decade—not as spectacular as the caliphate years, but persistent and deadly. December 2025’s airstrikes remind the world that complacency invites resurgence, and coordinated action remains essential to keeping the threat contained.
