A pair of suspected terrorist attacks on New Year’s Day are both believed to have been carried out by former US service members, raising questions about how those with access to sensitive intelligence and the country’s most advanced weapons become embroiled in radical beliefs.
Early Wednesday morning, reportedly a Texas resident, Shamsud-Din Jabbar plowed into a crowd on Bourbon Street in New Orleans, killing fourteen people. He was a former Army Staff Sergeant with a deployment to Afghanistan under his belt.
Hours later, a Tesla Cybertruck exploded in flames outside the Trump hotel in Las Vegas – a suspected terror plot linked to active duty Army Master Sgt. Matthew Livelsberger, who allegedly carried out the attack that led to his own death while on approved leave. He was a member of the elite Green Beret unit.
From 1990 to 2022, 170 individuals with a U.S. military background plotted 144 unique mass casualty terrorist attacks in the United States – 25% of all individuals who plotted extremist mass casualty crimes during this period, according to a study by the National Consortium for the Study of terrorism and responses to terrorism.

Questions posed to the Defense Department by Fox News Digital about its plans to identify and root out radicals went unanswered.
Here’s a look back at another one military radical extremists who have carried out attacks on US soil in the 21st century:
2009: Army psychiatrist Nidal Hassan kills thirteen people
In 2009, former Army Major Nidal Hassan killed thirteen people in a mass shooting at Fort Hood Army Base in Texas. The Islamic extremist and former army psychiatrist had spoken out about the American presence in Iraq and Afghanistan.
Retired Col. Terry Lee, who worked with Hassan, told Fox News that the Army major would make “bizarre” statements such as “the Muslims must stand up and fight the aggressor,” referring to U.S. troops.
Hassan reportedly shouted, “Allahu Akbar!” when he opened fire, killing 13 people and wounding 30 others in the deadliest mass shooting at a U.S. military base.
Hassan admitted to the murders in court is now on death row.

2021: Army soldier Cole James Bridges attempts to provide information to ISIS
In 2021, Army soldier Bridges, 24, was arrested for conspiracy to blow up the 9/11 memorial in New York and efforts to assist ISIS in killing American soldiers.
Now serving fourteen years in prison, Bridges was caught when he began communicating online with an undercover FBI agent he believed to be an ISIS supporter in contact with ISIS fighters in the Middle East.
2020: Army soldier Ethan Melzer provides information to a neo-Nazi group
Melzer, 24 at the time of his conviction, is serving 45 years in prison for sending sensitive US military information to the Order of the Nine Angles (O9A), an occult-based neo-Nazi and white supremacist group, in an attempt to facilitate a mass casualty attack on Melzer’s army unit.
He was arrested in 2020 after joining the military in 2018 to infiltrate its ranks and gain insight for his work for O9A. After being deployed to guard a remote, sensitive foreign US military base, he shared details of the location with O9A members and began calling for a deadly attack on his colleagues.
2014: Frazier Glenn Miller kills three outside Jewish centers
Miller, a lifelong white supremacist, shot and killed three people in Kansas in 2014, two outside a Jewish community center and one outside a Jewish retirement home.
Miller had spoken out about his intention to kill Jews, even though all his victims were Christians.
He served in the Army for twenty years, served two tours of duty in the Vietnam War and was a member of the elite Green Berets for thirteen years. After leading a chapter of the Ku Klux Klan, Miller had a history of run-ins with the law. He served three years in prison after being convicted in 1987 of conspiracy to acquire stolen military weapons and of planning robberies and an assassination attempt.
Miller has since died in prison.
