some wikipedia stuff:

Conservatism in the United States comprises a constellation of political ideologies including fiscal conservatism, free market or economic liberalism, social conservatism,[1] bioconservatism and religious conservatism,[2][3] as well as support for a strong military,[4] small government and promotion of states' rights.[5]


Generally, one could claim that European conservatives tend to be more moderate on many social and economic issues, than American conservatives. They tend to be quite friendly to the aims of the welfare state, although concerned about a healthy business environment. However, some groups have been more supportive of a stricter libertarian or laissez-faire agenda, especially under influence from Thatcherism. European conservative groups often see themselves as guardians of prudence, moderation, history and tried experience, as opposed to radicalism and social experiments. Approval of high culture and established political institutions like the monarchy is often found in European conservatism. Mainstream conservative groups are often staunch supporters of the European Union. However, one might also find elements of nationalism in many countries.
