On the eve of the 50th anniversary of the first U.S. military intervention in Lebanon, and 25 years after a second U.S. military intervention which left hundreds of Americans and thousands of Lebanese dead, the U.S. House of Representatives recently passed a resolution by a huge bipartisan majority which may lay the groundwork for a third one. At a minimum, this move has crudely and unnecessarily inserted the United States into Lebanon’s complex political infighting.
