Victor Davis Hanson has done a great job of tying together the actions of individuals and small groups with the same philosophy that drives the big-name terrorists like bin Laden or Zawahiri:
Why would Albanian-speaking Muslim refugees from the Balkans try to murder American soldiers? After all, the United States–not bin Ladens rag-tag jihadists–saved Bosnia and Kosovo? And we did that by bombing the capital of a Christian European nation.
But then, why did a mixed-up Albanian Muslim in Salt Lake City, one Sulejman Talovic, go on a shopping-mall shooting spree? Five innocents were killed in the attack before the murderer himself was shot and killed.
And why, after pouring billions of dollars into Afghanistan, did poor, mixed-up Omeed Aziz Popal, an Afghan Muslim, try to run over several innocents in San Francisco near a Jewish center in September 2006?
Or, for that matter, why did an angry Muslim Pakistani gun down Jews in Seattle?
Or, again, why earlier last year, did a 22-year-old Iranian-American Muslim drive his sport utility vehicle into a crowded pedestrian zone at the University of North Carolina?
Read the whole thing. Hanson discusses how an al Qaedist is created, the three-tiered war we are engaged in, and the limit of American patience.
