Hamilton and Madison thus had two major concerns: (1) the detrimental effect on liberty and democracy of a large standing army and (2) the ability of an unchecked legislature or executive to take the country to war precipitously. These concerns drove American military policy for the first century and a half of the country's existence. While armed forces were built up during wartime, the pattern after every war up to and including World War II was to demobilize quickly and return to something approaching pre-war force levels. However, with the advent of the Cold War in the 1950s, the need to create and maintain a sizable peacetime military force "engendered new concerns" of militarism and about how such a large force would affect civil–military relations in the United States.
