Soon the Cambodian Civil War erupted between Nol's government troops and the Khmer Rouge. Soon Nol was forced to ask the Americans for help. On November 18, 1970 US President Richard Nixon responded by asking the United States Congress for US$155 million in supplemental aid for the Cambodian government (US$85 million was for military assistance). Although Nol's government did receive the money it did not stop the Khmer Rouge.
Lon Nol fled into exile in Hawaii when the Communists seized power in Cambodia in 1975.
