“On June 22 [2001], U.S. military forces in the Persian Gulf and the Middle East were once again placed on alert after NSA [National Security Agency] intercepted a conversation between two al Qaeda operatives in the region, which indicated that ‘a major attack was imminent.’ All U.S. Navy ships docked in Bahrain, homeport of the U.S. Fifth Fleet, were ordered to put to sea immediately.”
