The December 1987 Reagan-Gorbachev summit raised once again the issue of linkage between Third World conflicts and East-West relations. Two broad questions are involved. First, how does the nuclear arms race intersect with social and political upheaval in the Third World? The second question involves the character of the East-West conflict as it affects the Third World, and the degree to which great power involvement can cause, exacerbate or potentially resolve conflicts in Asia, Africa and Latin America. A central maxim of much recent writing on East-West relations holds that the nuclear arms race is a means of regulating Third World conflict and impeding escalation to the point of war between the outside powers.
