Aberration? Or Same Old, Same Old.

There have been "lone wolf" mass murderers in which angry radical Muslims sought to channel their frustrations and failures into violence against their perceived enemies of Islam [in addition to the larger terror plots].

Since Sept. 11, several Muslim men have run over innocent bystanders or shot random people at or near military bases, synagogues and shopping malls.

After the initial hysteria died down, we were usually told that such acts were isolated incidents, involving personal "issues" rather than radical Islamic hatred of the U.S. Yet a few examples show that was not quite the case.

The just-executed sniper John Allan Muhammad, who, along with an accomplice, killed 10, voiced approval of Osama bin Laden and radical Islamic violence.

Naveed Afzal Haq is currently on trial for going on a murderous rampage at the Jewish Federation of Greater Seattle building. A survivor said Haq stated his attack was a "personal statement against Jews."

Mohammed Reza Taheri-azar ran over nine students at the University of North Carolina. Officers said he told them afterward he wanted to avenge the deaths of Muslims worldwide.

Omeed Aziz Popal struck 18 pedestrians with his car near a Jewish center in San Francisco. Witnesses say he said, "I am a terrorist," at the scene.

No doubt in each case, experts could assure us that there were extenuating personal circumstances — stresses and mental illnesses that better explain what happened.

Mere mention that such killers typically voiced radical Islamic or virulently anti-Semitic themes often can earn one charges of Islamaphobia, racism or other illiberal biases. Indeed, I expect dozens of angry, accusatory letters in response to this column.

Nevertheless, the facts since 9/11 reveal an undeniable reality.

Every few months either an Islamic-inspired terrorist plot will be foiled, or a young Muslim male will shoot, run down or stab someone while invoking anger at non-Muslims.

In other words, the attack on Fort Hood happened on schedule. It was the rule, not the exception. And something like it will occur again — soon.
