Abstract
We attempt to display a systematic approach for the distinction between states of equilibrium and disequilibrium in the interrelationships between nations, using as corroborative material the rapid shifts in 1956 among the various nations, brought about by the Middle Eastern situation. The psychological theory behind this approach is that of structural balance, which is pertinent in the present context to balance of power, while the logical framework involves the mathematical theory of graphs. We do not assert that this theory in its present form is predictive, but we do feel that it offers a well-organized mode of thinking which, although simple, may be fruitful. We also comment on some aspects of the Hungarian situation in terms of structural balance. It must be borne in mind throughout this article that it was written in early 1957 and that therefore the interrelationships among nations described herein reflect that time period.
