On August 21, just as the new U.S. Ambassador Henry Cabot Lodge Jr. arrived, Diem and his brother Ngo Dinh Nhu ordered South Vietnam forces, funded and trained by the CIA, to quell Buddhist demonstrations. The crackdowns heightened expectations of a coup d'état to remove Diem with (or perhaps by) his brother, Nhu. Lodge was instructed to try getting Diem and Nhu to step down and leave the country. Diem would not listen to Lodge. Cable 243 (DEPTEL 243) followed, dated August 24, declaring that Washington would no longer tolerate Nhu's actions, and Lodge was ordered to pressure Diem to remove Nhu. Lodge concluded that the only option was to get the South Vietnamese generals to overthrow Diem and Nhu. At week's end, orders were sent to Saigon and throughout Washington to "destroy all coup cables". At the same time, the first formal anti-Vietnam war sentiment was expressed by U.S. clergy from the Ministers' Vietnam Committee.
