Rustin maintained his strongly anti-Soviet and anti-communist views later in his life, especially with regard to Africa. Rustin co-wrote with Carl Gershman (a former director of Social Democrats, USA and future Ronald Reagan appointee) an essay entitled "Africa, Soviet Imperialism & the Retreat of American Power," in which he decried Russian and Cuban involvement in the Angolan Civil War and defended the military intervention by apartheid South Africa on behalf of the National Liberation Front of Angola (FNLA) and National Union for the Total Independence of Angola (UNITA). "And if a South African force did intervene at the urging of "black" leaders and on the side of the forces that clearly represent the "black" majority in Angola, to counter a non-African army of Cubans ten times its size, by what standard of political judgment is this immoral?" Rustin accused the Soviet Union of a classic imperialist agenda in Africa in pursuit of economic resources and vital sea lanes, and called the Carter Administration "hypocritical" for claiming to be committed to the welfare of blacks while doing too little to thwart Russian and Cuban expansion throughout Africa.
