Europe's most fearsome Muslim true believers are not products of the Israeli-Palestinian confrontation, or the First Gulf War, or the American troop presence in Saudi Arabia after 1990, or the Algerian civil war, or the Bosnian war, or the strife in Chechnya, or the Hindu pillaging of mosques, or the war in Afghanistan, or the second American war against Saddam Hussein, or the globalization of American culture. These events are banners that men who are already converted to jihad wave as they march to give battle. The holy warriors in Europe do not want to see peace in Palestine any more than Hamas's spiritual chief Ahmad Yassin or Osama bin Laden or Iran's clerical guide Ali Khamenei wants to see Israelis and Palestinians solve their problems in two separate, peacefully coexisting states. They do not care about Israeli settlements.

Europe's jihadists are born from their imperfect assimilation into Western European societies, from the particular alienation that young Muslim males experience in Europe's post-Christian, devoutly secular societies. The phenomenon is vastly more common among Arabs than among African or Asian Muslims. The reasons why these young, predominantly Arab males are drawn to the most militant expressions of Islam are complex and always personal. But their journey--which they usually begin as highly Westernized, modern-educated youths of little Islamic faith and end as practitioners of bin Ladenism--is a thoroughly European experience.

The jihadists of Europe have drunk deeply from the virulently anti-American left-wing currents of Continental thought and mixed it with the Islamic emotions of 1,400 years of competition with the Christian West. It's a Molotov cocktail of the third-world socialist Frantz Fanon and the Muslim Brother Sayyid Qutb. Muslims elsewhere have gone through similar conversions--the United States, too, has had its Muslim jihadists and will, no doubt, produce more. And the globalization of this virulent strain of fundamentalist, usually Saudi-financed, Islam is real and probably getting worse. But the modern European experience seems much more likely to produce violent young Muslims than the American. Europe may be competitive with the worst breeding grounds in Egypt, Saudi Arabia, and Pakistan.
