In United States politics, the radical right is a political preference that leans towards extreme conservatism, white supremacism, or other right-wing to far-right ideologies in a hierarchical structure paired with conspiratorial rhetoric alongside traditionalist and reactionary aspirations. The term was first used by social scientists in the 1950s regarding small groups such as the John Birch Society in the United States, and since then it has been applied to similar groups worldwide. The term "radical" was applied to the groups because they sought to make fundamental (hence "radical") changes within institutions and remove persons and institutions that threatened their values or economic interests from political life. Terminology Among academics and social scientists, there is disagreement over how right-wing political movement should be described, and no consensus over what the proper terminology should be exists, although the terminology which was developed in the 1950s, based on the use of the words "radical" or "extremist", is the most commonly used one. Other scholars simply prefer to call them "The Right" or "conservatives", which is what they call themselves. The terminology is used to describe a broad range of movements. The term "radical right" was coined by Seymour Martin Lipset and it was also included in a book titled The New American Right, which was published in 1955. The contributors to that book identified a conservative "responsible Right" as represented by the Republican administration of Dwight D. Eisenhower and a radical right that wished to change political and social life. Further to the right of the radical right, they identified themselves as the "ultraright", adherents of which advocated drastic change, but they only used violence against the state in extreme cases. In the decades since, the ultraright, while adopting the basic ideology of the 1950s radical right, has updated it to encompass what it sees as "threats" posed by the modern world. It has leveraged fear of those threats to draw new adherents, and to encourage support of a more militant approach to countering these perceived threats. A more recent book by Klaus Wahl, The Radical Right, contrasts the radical right of the 1950s, which obtained influence during the Reagan administration, to the radical right of today, which has increasingly turned to violent acts beginning with the Oklahoma City bombing in 1995. Wahl's book documents this evolution: "Ideologies of [today's] radical right emphasize social and economic threats in the modern and postmodern world
