"After the March 1st attack in Madrid, Spain, an Al Qaeda spokesman announced that 90 percent of the arrangements for an attack in the United States were complete.
The Madrid railway bombings were perceived by Osama bin Laden and al Qaeda to have advanced their cause. Al Qaeda may perceive that a large-scale attack in the United States this summer or fall would lead to similar consequences.Several upcoming events over the next few months may suggest especially attractive targets for such an al Qaeda attack.
