It's worse than you thought . . .

From an article in today's Boston Globe:

New investigations by the Saudi Arabian government and an Israeli think tank -- both of which painstakingly analyzed the backgrounds and motivations of hundreds of foreigners entering Iraq to fight the United States -- have found that the vast majority of these foreign fighters are not former terrorists and became radicalized by the war itself.

. . .

A separate Israeli analysis of 154 foreign fighters compiled by a leading terrorism researcher found that despite the presence of some senior Al Qaeda operatives who are organizing the volunteers, ''the vast majority of [non-Iraqi] Arabs killed in Iraq have never taken part in any terrorist activity prior to their arrival in Iraq."

. . .

American intelligence officials, speaking on the condition of anonymity, and terrorism specialists paint a similar portrait of the suicide bombers wreaking havoc in Iraq: Prior to the Iraq war, they were not Islamic extremists seeking to attack the United States, as Al Qaeda did four years ago, but are part of a new generation of terrorists responding to calls to defend their fellow Muslims from ''crusaders" and ''infidels."

. . .

''The president is right that Iraq is a main front in the war on terrorism, but this is a front we created," said Peter Bergen, a terrorism specialist at the nonpartisan New America Foundation, a Washington think tank.

. . .

Case studies of foreign fighters indicated they considered the Iraq war an attack on the Muslim religion and Arab culture, Paz said.

. . .

For example, while the unprovoked attacks of Sept. 11, 2001, were largely condemned by clerics as violations of Muslim law, many religious leaders in Saudi Arabia and other Arab nations have promulgated fatwas, or religious edicts, saying that waging jihad in Iraq is justified by the Koran because it is defensive in nature. Last October, 26 clerics in Saudi Arabia said it was the duty of every Muslim to go and fight in Iraq.

. . .

''These are people who did not get training in Pakistan or Chechnya, [and they] ended up going to Iraq because they considered defending Iraq a must for every Muslim to go and fight," said Rita Katz, director of the Search for International Terrorist Entities Institute in Washington and an Iraq native.

. . .

One indication that a heightened degree of Arab solidarity is a leading factor is that they are almost entirely Arabs and not Muslims from other countries, such as those who volunteered to fight in Afghanistan, Bosnia, and Chechnya. Another motivation, the studies and analysts contend, is the centuries-old struggle between the Sunni and Shia branches of Islam. All the foreign fighters are Sunnis, according to the analyses, and many of their targets are Iraq's majority Shia Muslims, who have gained political power in Baghdad for the first time in hundreds of years.

Pay extra attention to this comment:

'To say we must fight them in Baghdad so we don't have to fight them in Boston implies there is a finite number of people, and if you pen them up in Iraq you can kill them all," said Bergen. ''The truth is we increased the pool by what we did in Iraq."
