McVeigh had muzzy backing.....
Some investigators contend that Timothy McVeigh and his accomplice Terry Nichols had ties to Islamic terrorism through Ramzi Youssef, the Al Qaeda operative who planned the 1993 WTC bombing, and through a series of meetings with Islamic terror group Abu-Sayef members in the Philippines.
“Another conspiracy theory intrigued me because I could never disprove it. The theory seemed unlikely on its face: Ramzi Yousef or Khalid Sheik Muhammad had taught Terry Nichols how to blow up the Oklahoma Federal Building. The problem was that, upon investigation, we established that both Ramzi Yousef and Nichols had been in the city of Cebu on the same days. I had been to Cebu years earlier; it is on an island in the central Philippines. It was a town in which word could have spread that a local girl was bringing her American boy friend home and that the American hated the U.S. government.”
“Yousef and Khalid Sheik Muhammad had gone there to help create an al Qaeda spinoff, a Philippine affiliate chapter, named after a hero of the Afghan war against the Soviets, Abu Sayaff. Could the al Qaeda explosives expert have been introduced to the angry American who proclaimed his hatred for the U.S. Government? We do not know, despite some FBI investigation. We do know that Nichols’ bombs did not work before his Philippine stay and were deadly when he returned. We also know that Nichols continued to call Cebu long after his wife returned to the United States. The final coincidence is that several al Qaeda operatives had attended a radical Islamic conference a few years earlier in, of all places, Oklahoma City.”
