Pre U.S. Invasion of Iraq
Before the invasion of Afghanistan, Zarqawi was the leader of an Islamic militant group loosely affiliated with al-Qaeda. When Zarqawi first met bin Laden it was loathing at the first sight as bin Laden distrusted and disliked Zarqawi immediately. In an interview on Al-Majd TV, former al-Qaeda member Walid Khan, who was in Afghanistan fighting alongside Zarqawi's group explained that from the day al-Zarqawi's group arrived, there were disagreements, differences of opinion with bin Laden on a number of issues and positions. Bin Laden also suspected that many of Zarqawi's group members were Jordanian intelligence, disliked Zarqawi's swagger and the green tattoos on his left hand, which he reportedly considered un-Islamic and found Zarqawi hatred of Shiites divisive ). Saif al-Adel, now bin Laden's military chief, was an Egyptian who attempted to overthrow the Egyptian government saw merit in Zarqawi's overall objective of overthrowing the Jordanian monarchy. He intervened and smoothed the relations between Zarqawi and Al Qaeda leadership. It was agreed that Zarqawi will be given $5,000 U.S. dollars to start up his training camp outside the Afghan city of Herat, near the Iranian border. Zarqawi's camp would be as far away as he could be from bin Laden as Saif al-Adel was appointed as the middle man.
Zarqawi's group continued to received funding from Osama bin Laden but pursued "a largely distinct, if occasionally overlapping agenda," according to The Washington Post. Counterterrorism experts told the Washington Post that while Zarqawi accepted al-Qaeda's financial help to set up a training camp in Afghanistan he ran it independently and while bin Laden was planning September 11, Zarqawi was busy developing a plot to topple the Jordanian monarchy and attack Israel.
Nixon Center terrorism experts Robert S. Leiken and Steven Brooke explained that Zarqawi never meant to join al Qaeda. Militants have explained that Tawhid was especially for Jordanians who did not want to join al Qaeda. Even a confessed Tawhid member told his interrogators that Zarqawi was against al Qaeda. Zarqawi's men "refused to march under the banner of another individual or group" recalls Nu'man bin-Uthman, a Libyan Islamist leader now living in London who was in contact with Zarqawi at the time. Shortly after 9/11, a fleeing Ramzi bin al-Shibh, one of the main plotters of the attacks, appealed to Tawhid operatives for a forged visa. He could not come up with ready cash. Told that he did not belong to Tawhid, he was sent packing and eventually into the arms of the Americans.
The Washington Post also reported that German Intelligence wiretaps found that in the fall of 2001 that Zarqawi grew angry when his members were raising money in Germany for al-Qaeda's local leadership. "If something should come from their side, simply do not accept it," Zarqawi told one of his followers, according to a recorded conversation that was played at a trial of four alleged Zarqawi operatives in Duesseldorf.
At least five times, in 2000 and 2001, bin Laden called al-Zarqawi to come to Kandahar and pay bayat — take an oath of allegiance—to him. Each time, al-Zarqawi refused. Under no circumstances did he want to become involved in the battle between the Northern Alliance and the Taliban. He also did not believe that either bin Laden or the Taliban was serious enough about jihad. When the United States launched its air war inside Afghanistan, on October 7, 2001, al-Zarqawi joined forces with al-Qaeda and the Taliban for the first time. He and his Jund al-Sham fought in and around Herat and Kandahar. When Zarqawi finally did take the oath in October 2004, it was only after eight months of often stormy negotiations.
