Summary
On November 5, 2009, U.S. Army Major Nidal Malik Hasan opened fire at the Soldier Readiness Processing (SRP) center at Fort Hood, a major military installation near Killeen, Texas. Armed with a FN Five-seveN semi-automatic pistol and a .357 Magnum revolver, Hasan fired approximately 214 rounds in roughly ten minutes, killing 13 people and wounding 30 others before military police officers shot and incapacitated him. The victims included 12 soldiers and one civilian contractor, making it the deadliest mass shooting at a U.S. military installation in history.
Hasan, a 39-year-old Army psychiatrist assigned to Fort Hood’s Darnall Army Medical Center, had been due to deploy to Afghanistan. Though a U.S.-born Muslim of Palestinian descent, he had become increasingly radicalized in the years leading up to the attack. In the months before the shooting, he exchanged a series of emails with Anwar al-Awlaki, a prominent al-Qaeda-affiliated cleric based in Yemen, which were monitored by the FBI’s Joint Terrorism Task Force. Investigators reviewed the correspondence but concluded at the time that Hasan’s questions were consistent with legitimate research into the experiences of Muslim soldiers — a judgment later heavily criticized.
Though he survived his wounds, Hasan was paralyzed from the chest down. He was charged with 13 counts of premeditated murder and 32 counts of attempted premeditated murder. Court-martialed in August 2013, Hasan represented himself and offered no defense, calling no witnesses. The jury convicted him on all 13 murder counts and sentenced him to death. As of 2024 he remains on military death row at the U.S. Disciplinary Barracks at Fort Leavenworth, Kansas.
Background: Radicalization and Missed Warnings
Hasan was born in 1970 in Arlington, Virginia, to Palestinian immigrant parents. He joined the Army after high school, obtained his medical degree through the Uniformed Services University of the Health Sciences, and completed a psychiatry residency, reaching the rank of Major by 2009. Colleagues and supervisors later described a pattern of increasingly extremist statements stretching back years — including a PowerPoint presentation in 2007 in which he argued that Muslim soldiers should be granted conscientious-objector status and warned of potential “adverse events” if Muslims were forced to fight fellow Muslims.
Between December 2008 and June 2009, Hasan sent between 10 and 18 emails to Anwar al-Awlaki, asking questions about the permissibility under Islam of killing American soldiers in defense of Islam and whether suicide bombing was justified. Al-Awlaki, who had been under FBI surveillance, responded to several of the messages. The FBI’s Washington Field Office reviewed the correspondence in coordination with the Army’s counterintelligence unit but did not escalate the matter, concluding Hasan’s queries were research-related. A subsequent Senate investigation found this to be a significant intelligence and law-enforcement failure.
The Attack
At approximately 1:34 p.m. on November 5, 2009, Hasan entered the crowded SRP center — a facility where soldiers processed paperwork before and after deployment — and opened fire. Witnesses reported he shouted “Allahu Akbar” before beginning to shoot. Hasan moved through the building methodically, firing at soldiers who were unarmed as per base policy in administrative areas.
Civilian police officer Sergeant Kimberly Munley arrived within three minutes and exchanged fire with Hasan, wounding him but also sustaining gunshot wounds herself. Sergeant Mark Todd, a second responding officer, then shot Hasan four more times, incapacitating him. The entire active-shooting episode lasted approximately ten minutes. The SRP center’s layout — a large gymnasium-style space with limited exits — contributed to the high casualty count, as soldiers had little cover and no weapons with which to respond.
Investigation and Legal Proceedings
A joint Senate investigation released in February 2011 concluded that the FBI and Army had failed to act on “clear and persuasive information” that Hasan had “embraced views so extreme that it should have been apparent he might take violent action against his fellow soldiers.” The report identified 26 specific opportunities at which law-enforcement and military authorities could have intervened. It also criticized the culture of reluctance to report a colleague due to concerns about appearing discriminatory.
In the trial, Hasan acknowledged carrying out the attack and stated his motive was to protect Taliban and al-Qaeda fighters from American soldiers. The court-martial took less than two weeks; the jury of senior military officers deliberated for approximately seven hours before convicting Hasan on all counts and voting unanimously for the death penalty.
Policy Aftermath
The Department of Defense initially classified the Fort Hood shooting as an incident of “workplace violence” rather than terrorism, a categorization that denied the victims eligibility for the Purple Heart medal awarded for combat wounds and the corresponding benefits. This classification was widely condemned by survivors and victims’ families, by members of Congress across both parties, and by military advocacy organizations.
Section 571 of the Carl Levin and Howard P. “Buck” McKeon National Defense Authorization Act for Fiscal Year 2015 expanded Purple Heart eligibility to include attacks inspired or motivated by a foreign terrorist organization where the perpetrator had been in communication with that organization beforehand. This change made the Fort Hood victims eligible: in 2015 the Army awarded the Purple Heart to the military victims and the Defense of Freedom Medal to the civilian victims, and the surviving wounded and the families of the deceased were retroactively recognized. Because combat-related casualties carry different benefit and tax provisions than those classified as workplace injuries, the reclassification also affected the financial benefits available to the victims and their families.
Significance
The Fort Hood shooting prompted a thorough review of how the U.S. military and federal law enforcement identify, report, and respond to radicalization within the armed forces. The Bipartisan Policy Center and Senate Homeland Security Committee published detailed reports criticizing institutional reluctance to act on behavioral warning signs when racial or religious profiling concerns might be raised. The incident contributed to the revision of the DoD Insider Threat program and updated threat-assessment protocols for military psychiatrists and other personnel in positions involving access to classified material and military personnel records.
More broadly, the attack became a landmark case in debates over “homegrown” or “lone-wolf” terrorism — radicalized individuals acting within the United States with ideological inspiration but limited operational direction from foreign groups. Hasan’s email correspondence with al-Awlaki illustrated how open-source radical content and direct digital contact with clerics abroad could radicalize a U.S. citizen without the traditional operational infrastructure of a terrorist cell.
The Fort Hood tragedy also intersected with the early months of the Barack Obama administration’s national security posture. It occurred just weeks before the December announcement of Obama’s Afghanistan surge strategy, and deepened public and congressional scrutiny of both intelligence-sharing protocols between the FBI and military and the ongoing challenges of the wars in Iraq and Afghanistan. The Obama Nobel Peace Prize controversy, announced in October 2009, had already put Obama’s war-versus-diplomacy balance in sharp relief when the Fort Hood attack occurred.
