Cuba has approximately 35,000 troops in Africa today. Relative to its population, that is comparable to U.S. involvement in Vietnam at the height of the war. The Cuban military presence in Africa, with Soviet support, has become a major and divisive concern of the Carter Administration, leading in the spring of 1978 to a public shouting match between Presidents Castro and Carter over the degree of Cuban involvement in the invasion of Zaïre's Shaba province by former Katanga gendarmes based in Angola.
In the debate on how to respond to Cuban overseas activities, a major argument is whether Cuba has a foreign policy of its own.

Cuba is a small country, but it has a big country's foreign policy. It has tried to carry out such a policy since the beginning of the revolution, but only in the second half of the 1970s did it have the conditions - internal resources, lack of U.S. opposition, and an African context that welcomed what Cuba seemed best able to provide - to become a visible and important actor actually shaping the course of events.

In 1959-60, suspicion hardened into hostility and serious disputes emerged with the United States, and for nearly a decade thereafter Washington, as we know, literally
