Neoconservatism - "a somewhat controversial term referring to the political goals and ideology of the "new conservatives" in the United States. The "newness" refers either to being new to American conservatism (often coming from liberal or socialist backgrounds) or to being part of a "new wave" of conservative thought and political organization."
Neoliberalism - "used to describe a political-economic philosophy that had major implications for government policies beginning in the 1970s – and increasingly prominent since 1980 – that de-emphasizes or rejects positive government intervention in the economy, focusing instead on achieving progress and even social justice by encouraging free-market methods and less restricted operations of business and "development". Its supporters argue that the net gains for all under free trade and capitalism will outweigh the costs in all, or almost all, cases."
Conservativism - "1. Classical conservatism or institutional conservatism - Opposition to rapid change in governmental and societal institutions. This kind of conservatism is anti-ideological insofar as it emphasizes means (slow change) over ends (any particular form of government). To the classical conservative, whether one arrives at a right- or left-leaning government is less important than whether change is effected through rule of law rather than through revolution and sudden innovation.
2. Ideological conservatism or right conservatism - In contrast to the anti-ideological classical conservatism, right conservatism is, as its name implies, ideological. It is typified by three distinct subideologies: social conservatism, fiscal conservatism, and economic conservatism. Together, these subideologies comprise the conservative ideology in most English-speaking countries: separately, these subideologies are incorporated into other political positions.
* Social conservatism is generally dominated by defence of existing social norms and values, of local customs and of societal evolution, rather than social upheaval, though the distinction is not absolute. Applied to foreign policy, a mild social conservatism manifests itself in Rudyard Kipling's defence of the Indian natives against British imperialism and in American opposition to the "forced democratization" of post-war Iraq, but conversely, betraying the complexity of ideology, the vast majority of American conservatives in keeping with their accepted values fully support the current effort at democratization (which many conservatives claim as a liberation, in the sense that liberty increases dramatically). In its more extreme foreign-policy manifestations, social conservatism breeds nationalism, tending towards isolationism, on the order of Pat Buchanan's anti-immigration, anti-internationalist stance.
* Fiscal conservatism is the stance that the government must "live within its means". Above all, fiscal conservatives oppose excessive government debt; this belief in balanced budgets tends to be coupled with a belief that government welfare programs should be narrowly tailored and that tax rates should be low, which implies relatively small government institutions.
* This belief in small government combines with fiscal conservatism to produce a broader economic conservatism, which wishes to minimize government intervention in the economy. This amounts to support for laissez-faire economics. This economic conservatism borrows from two schools of thought: the classical conservative's pragmatism and the libertarian's notion of "rights." The classical conservative maintains that free markets work best, while the libertarian contends that free markets are the only ethical markets."
Liberalism - "a political current embracing several historical and present-day ideologies that claim defense of individual liberty as the purpose of government. It typically favors the right to dissent from orthodox tenets or established authorities in political or religious matters. In this respect, it is sometimes held in contrast to conservatism. Since liberalism also focuses on the ability of individuals to structure a society, it is almost always opposed to totalitarianism, and often to collectivist ideologies, particularly communism and, in some cases, socialism."
