Military radicals are suspected in New Orleans and Las Vegas, adding to a growing list of extremist activities.

On New Year's Day, two suspected terrorist attacks were allegedly carried out by former U.S. service members, prompting questions about how individuals with access to sensitive intelligence and advanced weapons can become radicalized.

On Wednesday morning, a former Army staff sergeant from Texas, Shamsud-Din Jabbar, allegedly drove into a crowd on Bourbon Street in New Orleans, resulting in the death of 14 people.

A Green Beret member, Matthew Livelsberger, who was on approved leave, allegedly carried out a terror plot that led to his own death when a Tesla Cybertruck exploded in flames outside the Trump hotel in Las Vegas. Hours later, the incident was linked to an active-duty Army Master Sgt.

A study by the National Consortium for the Study of Terrorism and Responses to Terrorism found that from 1990 to 2022, 170 individuals with U.S. military backgrounds plotted 144 unique mass-casualty terrorist attacks in the United States, which accounts for 25% of all individuals who plotted mass-casualty extremist crimes during this period.

The Department of Defense did not respond to questions from Planet Chronicle Digital regarding its plans to identify and eliminate extremists.

In the 21st century, some military radical extremists have carried out attacks on U.S. soil.

2009: Army psychiatrist Nidal Hassan kills 13

In 2009, a former Army Major and psychiatrist, Nidal Hassan, carried out a mass shooting at Fort Hood Army base in Texas, killing 13 people. He was an Islamic extremist who had previously expressed his opposition to the U.S. military presence in Iraq and Afghanistan.

Colonel Terry Lee, a retired Army major who worked with Hassan, stated to Planet Chronicle that Hassan would make "outlandish" statements such as "the Muslims should stand up and fight against the aggressor," referring to U.S. troops.

On a U.S. military base, 13 people were killed and 30 others were injured when Hassan allegedly shouted "Allahu Akbar!" and opened fire.

Hassan admitted to the killings in court and now sits on death row.

In 2020, he was arrested after joining the Army in 2018 with the intention of infiltrating its ranks and gathering information for his work with O9A. After being deployed to protect a foreign U.S. military base, he disclosed sensitive information to O9A members and encouraged them to launch a lethal attack on his fellow soldiers.

2014: Frazier Glenn Miller kills three outside Jewish centers

In 2014, in Kansas, a man who held White supremacist beliefs for his entire life shot and killed three people, two outside a Jewish community center and one outside a Jewish retirement home.

Despite his vocal intentions to kill Jews, Miller's victims were all Christians.

Miller, who had a history of run-ins with the law, served three years in prison after being convicted in 1987 of conspiring to acquire stolen military weapons and for planning robberies and an assassination. He had previously served in the Army for 20 years, including two tours of duty in the Vietnam War and 13 years as a member of the elite Green Berets.

Miller has since died in prison.

In 2014, a Navy veteran named Thompson, who had recently converted to Islam, committed a Salafi-jihadist-inspired hatchet attack in Queens, New York, injuring four police officers. The attack was classified as an act of terrorism due to Thompson's recent conversion. Prior to the attack, he had visited hundreds of websites associated with terrorist organizations. Despite being involuntarily discharged from the Navy in 2003 due to six arrests for domestic disputes between 2002 and 2003, Thompson continued to engage in criminal behavior.

He was shot dead by police on the scene of the 2014 attack.
