As noted above, almost immediately after September 11, credible reports emerged of Israeli warnings, in August 2001, of an imminent large-scale terrorist attack on the United States. One television network reported in a four-part series in December 2001 that —

"Investigators suspect that the Israeli [DEA Groups] may have gathered intelligence about the attacks in advance, and not shared it. A highly placed investigator said there are 'tie-ins.' But when asked for details, he flatly refused to describe them, saying 'evidence linking these Israelis to 9-11 is classified. I cannot tell you about evidence that has been gathered. It's classified information.'" ⁷⁴

The Forward, the highly respected American journal, at first discounted Fox's account, ⁷⁵ but in an article three months later reported that —

"[F]ar from pointing to Israeli spying against U.S. government and military facilities . . . the incidents in question [the activities of the Israeli DEA Groups] appear to represent a case of Israelis in the United States spying on a common enemy, radical Islamic networks suspect of links to Middle East terrorism. . . . [A]llegations involved . . . Israelis claiming to be art students who had backgrounds in signal interception and ordnance." ⁷⁶

It is very difficult to believe, based on the existing evidence and the location of their common central operating bases, that these Groups, who were clearly spying on the DEA and the United States, and were keeping under surveillance Islamic groups in the U.S. with links to Middle East terrorism, were not tracking the future hijackers and their collaborators as well.
