It is not democracy that keeps western nations at war, but armies and the interests now massed behind them. The greatest speech about modern defence was made in 1961 by the US president Eisenhower. He was no leftwinger, but a former general and conservative Republican. Looking back over his time in office, his farewell message to America was a simple warning against the "disastrous rise of misplaced power" of a military-industrial complex with "unwarranted influence on government". A burgeoning defence establishment, backed by large corporate interests, would one day employ so many people as to corrupt the political system. (His original draft even referred to a "military-industrial-congressional complex".) This lobby, said Eisenhower, could become so huge as to "endanger our liberties and democratic processes".
