The bulletin also notes the Iraq-based master terrorist's apparent belief that "if an individual has enough money, he can bribe his way into the U.S.," specifically by obtaining a "visa to Honduras" and then traveling across Mexico and the southern U.S. border.
Al-Zarqawi's aide also revealed that his boss, after pondering the absence of attacks in the U.S. in recent years, concluded that a lack of "willing martyrs" was to blame. Al-Zarqawi believes, according to his lieutenant, that "if an individual is willing to die, there was nothing that could be done to stop him," even in the U.S. There is no evidence, say intelligence agencies, that al-Zarqawi's agents have infiltrated the U.S. But authorities remain vigilant.
Security sources tell TIME that just last week the FBI sent out two nationwide bulletins warning of a nonspecific threat to railroads in Detroit and Los Angeles. On her visit to Mexico last week, Secretary of State Condoleezza Rice issued her own reminder of the border's vulnerability. "There's no secret," Rice told reporters, "that al-Qaeda will try to get into this country ... by any means they possibly can."
