It is one of nature's ironic mercies that the same disease responsible for disfiguring Sheik Omar Abdel-Rahman's face left him blind, thereby sparing him the sight of his Gorgon-like features. The sheik died from complications of that disease – diabetes – at age 78 in a federal prison cell in North Carolina, a peaceful end to a long life largely devoted to terrorist violence. He had lived at taxpayer expense for roughly one-third of that life. For the better part of a decade prior to his June 1993 arrest, Sheik Omar had covertly been on the federal payroll as a CIA asset.

Abdel-Rahman was the "spiritual leader" of the terrorist cell that carried out the February 26, 1993 bombing of the World Trade Center in New York City. Six people were killed in that attack, which inflicted $500 million in damage and would have been apocalyptic in scope if the bomb-laden Ryder truck used in the plot had been placed in the proper section of the basement parking garage. The plan was to send one of the towers toppling into the other.

A native Egyptian, Sheik Omar boasted of his involvement in the assassination of President Anwar Sadat in 1981. Six years later the U.S. State Department placed Sheik Omar's name on its "watch list" of non-Americans believed to be involved in terrorism. That did not prevent the CIA from enlisting Sheik Omar as a "valuable asset" in covert operations involving the Afghan mujahideen during the 1980s.

Between 1980 and 1989, the CIA pumped more than $3 billion in aid into the Islamic resistance to the Soviet occupation of Afghanistan. Following more than a decade and a half of combat in that country, Americans have come to understand how tenaciously Afghans fight to expel foreign occupiers – and the fact that the country's tribal culture is an impenetrable mare's nest. It should also be clear by now that the CIA has an uncanny instinct for supporting the worst of the contending factions in any country upon which its gaze descends.  Author Kurt Lohbeck documented in his study Holy War, Unholy Victory: Eyewitness to the CIA's Secret War in Afghanistan that during the mid-1980s the CIA invested most of its aid in the least combat-worthy and most anti-American factions of the mujahideen. Among the CIA's dubious beneficiaries was Sheik Omar.

Writing in the May 1996 issue of The Atlantic Monthly, foreign correspondent Mary Anne Weaver recalled that it was in Peshawar, Pakistan, that Sheik Omar "became involved with U.S. and Pakistani intelligence officials who were orchestrating the war" against the Soviets, and that the "sixty or so CIA and Special Forces officers based there considered him a 'valuable asset' … and overlooked his anti-Western message and incitement to holy war because they wanted him to help unify the mujahideen groups."

Sheik Omar and his associates created an institution in Peshawar, Pakistan, called the Service Office, which recruited Muslims from around the world as volunteers to fight the Soviets in Afghanistan. Branches of the Service Office were created throughout Europe and the United States, thereby providing a ready slush fund for terrorists and anti-Western agitators. While the Service Office sluiced money into the coffers of terrorists, Sheik Omar preached his gospel of jihad in Pakistan, Egypt, and Saudi Arabia, and in Islamic population centers in Turkey, Germany, England, and even the United States — despite his listing on the State Department's "watch list."

Sheik Omar's status as a "valuable asset" to the CIA didn't end after the Red Army vacated Afghanistan in early 1989.

On May 10, 1990, Sheik Omar was granted a one-year visa from a CIA agent posing as an official at the U.S. Consulate in Khartoum, Sudan, and he arrived in New York in July 1990. In November of the same year Sheik Omar's visa was revoked, and the State Department advised the Immigration and Naturalization Service to be on the lookout for him. So attentive was the INS to this advisory that it granted Sheik Omar a green card just five months later.

This wasn't a failure of the vetting procedure. It was the peculiar kind of "success" that often facilitates the arrival of capable practitioners of violence who are useful for the Deep State's domestic operations.

The American-based radicals who sponsored Sheik Omar's 1990 trip to the U.S. included Mahmud Abouhalima, a CIA-supported veteran of the Afghan campaign. Also helping to make arrangements for the sheik's visit was Mustafa Shalabi, the Brooklyn-based director of Alkifah, a support fund for mujahideen fighters. Another leader of Sheik Omar's American network was El Sayyid Nosair, an Egyptian expatriate who went on to murder Jewish nationalist Rabbi Meir Kahane.

Abouhalima and Nosair were eventually among those convicted of conspiring with Sheik Omar to wage urban warfare in the United States, and in that campaign they made use of skills imparted to them by the CIA and the U.S. military.

During the 1995 conspiracy trial, attorneys for Sheik Omar and his disciples introduced a file documenting that in 1989, the U.S. Army had sent Special Forces Sergeant Ali A. Mohammed – who had been cashiered from the Egyptian Army several years earlier — to Jersey City to provide training for mujahideen recruits, including Abouhalima and Nosair. Although Omar was regarded as the cabal's spiritual leader, and Nosair was said to be the signal-caller, US Attorney Patrick Fitzgerald believed that Mohammed was the chief architect of "al-Qaeda's terrorist infrastructure in the U.S."

In March 2001 – a few months before the immeasurably bloodier encore at the World Trade Center – Mohammed pleaded guilty to charges arising from the 1998 bombings of US embassies in Kenya and Tanzania, in which 258 people were murdered. He was then allowed to flee the jurisdiction without being sentenced.

Mohammed's main role in the 1993 plot was to train and supervise the others. According to Two Seconds Under the World, a book on the 1993 WTC bombing co-written by Newsday's Pulitzer-winning investigative team, all of this was done under constant FBI surveillance. The Bureau had ample advance notice of what Sheik Omar's disciples intended to do.
