33 years ago, three spectacular attacks in Beirut over an 18-month period announced the debut of a potent new force in Lebanon-the Shiite Hezbollah militia- and defined its relationship with the United States for years to come. The October 1983 bombings of Multinational Force bases took the lives of 241 Americans and 58 French. Beirut, a city battered by war, was experiencing a period of relative calm in fall 1983. U.S. diplomats and soldiers were still coming to terms with the suicide bombing that struck the U.S. embassy in April, and U.S. Marines wore their combat uniforms everywhere they went-even to social events and diplomatic functions. But to the U.S. Marine commander on site, the threat environment seemed to have eased somewhat. The embassy bombing was seen as an outlier event. Marines were free to roam the city and were interacting with Lebanese children in public without fear of ambush. Beirut was under a cease-fire, and hopes were high for Syrian reconciliation talks. It was the quiet before the storm.
