The purpose of this thesis is to discover the effects of Soviet interventions on overall voting patterns in the General Assembly of the United Nations. Specifically, it endeavors to study how U.N. voting changed after the Soviet invasions into Hungary in 1956, Czechoslovakia in 1968 and Afghanistan in 1979. The hypotheses of this study state that violations of the norm of national self-determination by the USSR (i.e. the interventions) will lead to less cordial relations between the Soviet Union and other nations. Countries classified as neutral during the periods prior to each invasion as well as members of the non-aligned movement are separated from the other nations of the U.N. for special study. Regression analysis of General Assembly Roll Call data shows that only in the case of Hungary did any change in voting behavior take place.
