The document discusses several Cold War conflicts outside of the major US-Soviet confrontations in Korea, Cuba, and Vietnam. It describes how the US opposed Communist influences in Nicaragua, Iran, and Afghanistan in line with its containment policy. In Nicaragua, the US initially supported the Somoza dictatorship but later backed anti-Communist Contras against the Sandinista government. In Iran, the US aided the Shah's Western-backed regime until the 1979 Iranian Revolution established an anti-American Islamic state under Ayatollah Khomeini. The Soviet invasion of Afghanistan in the 1970s to prop up a Communist government also drew US support for anti-Soviet Muslim rebels.
