York Times Book Review. Isaiah Bowman commented in 1942, "On grounds of merit and public value America’s Strategy in World Politics should be read in not less than a million American home. Every government official responsible for policy should read it once a year for the next twenty years—even if he may not agree with some of the remedies proposed." The Geography of the Peace was published the year after Spykman's death. He explained his geostrategy and argued that the balance of power in Eurasia directly affected US security. In his writings on geography and foreign policy, Spykman was somewhat of a geographical determinist. Since geography was "the most fundamentally conditioning factor because of its relative permanence," it is of primary relevance in analyzing a state's potential foreign policy. However, Spykman rejected that geography had a "deterministic, causal role in foreign policy, arguing, neither does the entire foreign policy of a country lie in geography, nor does any part of that policy lie entirely in geography. The factors that condition the policy of states are many; they are permanent and temporary, obvious and hidden; they include, apart from the geographic factor, population density, the economic structure of the country, the ethnic composition of the people, the form of government, and the complexes and pet prejudices of foreign ministers; and it is their simultaneous action and interaction that create the complex phenomenon known as "foreign policy."According to Spykman, topography affected the unity and internal coherence of states, and climate affected the economic structure of the state. Spykman argued that the "comparative size of states" was a rough indication of the comparative strength of states (provided that there was political and economic integration of the state). He also argued that "Size is of primary importance as an element of defense, particularly if the vital centers of a country are far removed from the border." He wrote that all states tend towards expansion, "Other things being equal, all states have a tendency to expand." Even small states seek to expand, but are limited in doing so by various barriers. Death He died of heart complications on 26 June 1943, at the age of 49, in New Haven, Connecticut, a result of kidney disease contracted when young. Personal life He was married to the children's novelist E. C. Spykman. Geostrategic ideas He could be considered as a disciple and critic of both geostrategists Alfred
