convinced by their arguments, and spoke out against the plan, shocking some of his liberal allies. Koch was active in advocating for a greater U.S. role in advancing human rights within the context of fighting Communism. He had particular influence in the foreign aid budget, as he sat on the House Appropriations Subcommittee on Foreign Operations. In 1976, Koch proposed that the U.S. cut off military aid and supplies to the military dictatorship of Uruguay. In mid-July 1976, the CIA learned that two high-level Uruguayan intelligence officers had discussed a possible assassination attempt on Koch by Dirección de Inteligencia Nacional (DINA), the Chilean secret police under dictator Augusto Pinochet.

Koch also dealt with the second transit strike, and pushed for the 1980 Democratic National Convention to be in NYC. His first term also saw a sister city relationship begin with Beijing. Second term Among the events of Koch's second term as mayor were the Brooklyn Bridge's 100th anniversary, the appointing of Benjamin Ward as the city's first ever African American police commissioner in 1983, the emergence of AIDS as a public health crisis, extensive media coverage of Bernhard Goetz's shooting of four African American teenagers in the subway in 1984, and the United Nations' 40th anniversary. Koch often deviated from the conventional liberal line, strongly supporting the death penalty, adding 3,500 officers to the NYPD in the 1980s, and taking a hard
