 In 1949, under U.S. President Harry Truman, a coup overthrew an elected parliamentary government in Syria, which had delayed approving an oil pipeline requested by U.S. international business interests in that region.The exact role of the CIA in the coup is controversial, but it is clear that U.S. governmental officials, including at least one CIA officer, communicated with Husni al-Za'im, the coup's organizer, prior to the March 30 coup and were at least aware that it was being planned.Six weeks later, on May 16, Za'im approved the pipeline.
