(The Center Square) – In 1993, Islamic terrorists detonated a truck filled with explosives at the World Trade Center in Manhattan. Five years later, a related group, al Qaeda, bombed two U.S. embassies in Africa.

Despite the ominous signs, “none of the measures adopted by the U.S. government disturbed or even delayed the progress of the al Qaeda plot” that culminated in the Sept. 11, 2001, attacks that killed 2,977 Americans.
