The balance of threat theory was proposed by Stephen Walt in his article ''Alliance Formation and the Balance of World Power'', published in the journal ''International Security'' in 1985. He elaborated it in his book, ''The Origins of Alliances'' (1987). The theory modified the popular balance of power theory in the neorealist school of international relations.

Walt contends that states generally balance by allying against a perceived threat, while very weak states are more likely to bandwagon with the rising threat to protect their own national security. He points to the example of the alliance patterns of European states before and during World War I and World War II, when nations with a significantly-greater combined power allied against the recognized threat of German expansionism. Walt identifies four criteria states use to evaluat ...
