Irving Kristol argued that 'there is no set of neoconservative beliefs concerning foreign policy'.

The neoconservative movement had a significant effect on the course of American foreign policy after the September 11th terrorist attacks.

The Neoconservative movement provided senior advisors to the Bush administration, whose sense of moral superiority and vision for a democratized, Saddam-free Middle East guided the administration's foreign policy after 9/11, a response that was linked to neocon persuasion.

Irving Kristol provided a defining quote about neoconservatism in 1983.

Described as the 'accredited Godfather of neoconservatism', he defined the ideology as a 'persuasion', and his claims about American foreign policy were central to the formulation of the neoconservative psyche.

Francis Fukuyama's analysis explained what neoconservatism stood for during its earliest incarnation, arguing that four common principles characterized the neoconservative movement up until the end of the Cold War, contributing to the understanding of the movement.
