Guess the nationality of a majority of the foreign fighters in Iraq

Iraqi? Iranian? Syrian?

Nope. Saudi.

Yes, Saudi Arabia, led by George W. Bush's tiptoeing through the tulips buddy, is contributing 55% of the foreign fighters who are now killing our troops:

An NBC News analysis of hundreds of foreign fighters who died in Iraq over the last two years reveals that a majority came from the same country as most of the 9/11 hijackers — Saudi Arabia.

Among the suicide bombers was Ahmed al-Ghamdi, a one-time medical student and son of a Saudi diplomat. In December 2004, he climbed into a truck in Mosul and blew himself up.

On an Internet video, another Saudi says goodbye to his mother, then drives an ambulance full of explosives into a building.

They are among more than 400 militants from 21 countries whose deaths were celebrated on Islamic Web sites over the last two years.

"By far the nationality that comes up over and over again is Saudi Arabia," says Evan Kohlmann, an NBC News terrorism expert.

The NBC News analysis of Web site postings found that 55 percent of foreign insurgents came from Saudi Arabia, 13 percent from Syria, 9 percent from North Africa and 3 percent from Europe.
