“On May 26, 2009, one of the most sensitive reports from the world of deep intelligence appeared in the TOP SECRET/CODEWORD President’s Daily Brief [PDB]. …The headline on this item read, ‘North American al Qaeda trainees may influence targets and tactics in the United States and Canada.’ This report, and another highly restricted one, said that at least 20 al Qaeda converts with American, Canadian or European passports were being trained in Pakistani safe havens to return to their homelands to commit high-profile acts of terrorism. They included half a dozen from the United Kingdom, several Canadians, some Germans and three Americans. None of their names was known.”
