Interviews with Abu Ibrahim and relatives of the other men show that rather than having been individually recruited by an organization like Zarqawi's, they gradually radicalized one another, the more strident leading the way. Local imams led them further toward Iraq, citing verses from the Koran to justify killing civilians. The men watched videos depicting tortured and slain Muslims that are copied from Internet sites.
"The sheik, he was a hero," Abu Ibrahim said of Zarqawi. But, he added, "I decided to go when my friends went."
For the final step, getting the phone number of a smuggler and address of a safe house in Iraq, the men used facilitators who act more like travel agents than militant leaders.
"Most of the young people here in Zarqa are very religious," an Islamist community leader said. "And when they see the news and what is going on in the Islamic countries, they themselves feel that they have to go to fight jihad. Today, you don't need anyone to tell the young men that they should go to jihad. They themselves want to be martyrs."
