Graham Allison writes political science and foreign-policy analysis about nuclear decision-making, government bureaucracy and great-power rivalry. Essence of Decision uses the Cuban Missile Crisis to compare different models of how governments make choices, showing how organisational routines and bureaucratic interests can produce outcomes that a single-rational-actor model misses. Destined for War popularised the phrase Thucydides's Trap for situations in which a rising power challenges an established one, applying it primarily to the United States and China. Allison's prose moves between case study and policy argument, with historical comparison used to frame contemporary strategic risk. His work fits international relations, security studies and decision-making, particularly for readers interested in how institutions complicate apparently straightforward foreign-policy choices.
