So much of social science is dependent on various actors making rational decisions. Economics has regularly proven that “actors” certainly fail to act rationally as manias, crashes and panics in repeated form are proof (see Charles Kindleberger). In the realm of politics, the dependence on nation-states to behave rationally has led to many major policy errors. During the Cold War the balance of nuclear weapons prompted both super powers to remain reticent to embark on direct confrontations and avoid an unthinkable shooting war. The fear of world destruction also meant that the USSR and UNITED STATES would leash their “allies” to prevent any direct conflict between the two major hegemonists.
