Peace through strength
"Peace through strength" is a phrase and theory that a sufficiently strong military can preserve peace. The concept has long been associated with realpolitik and deterrence theory. The phrase probably originates with Neville Chamberlain who ran a 'Peace Through Strength' public relations campaign from 1936–1939 to avoid World War II; the phrase then gained currency during the Cold War, eventually becoming a core policy tenet of the United States Republican Party since 1980. The idea has critics, with Andrew Bacevich stating, "'Peace through strength' easily enough becomes 'peace through war.'"
