During his subsequent trial, Hasan admitted to the shooting and claimed it was necessary to protect the "Islamic Empire" from American forces.
The Pentagon had categorized the massacre as an act of "workplace violence," a decision that drew sharp criticism from lawmakers, victims’ families, and national security experts. They argued it obscured the ideological and terrorist motivations behind the attack.
In 2013, a military jury convicted Hasan and sentenced him to death.

Hasan, born in Arlington, Virginia, in 1970 to Palestinian immigrant parents, served nearly 20 years in the Army before reportedly embracing radical Islamist beliefs.
By the time he was stationed at Fort Hood in 2009, he had become outspoken in his opposition to U.S. military campaigns in Iraq and Afghanistan, justifying suicide bombings as legitimate acts of war.
