新保守主義はいつ頃から提唱されだした？
Neoconservatism (commonly shortened to neocon when labelling its adherents) is a political movement born in the United States during the 1960s among liberal hawks who became disenchanted with the increasingly pacifist foreign policy of the Democratic Party, and the growing New Left and counterculture, in particular the Vietnam protests. Some also began to question their liberal beliefs regarding domestic policies such as the Great Society.
