Do any countries in the world currently practice National Socialism as their government?
No. Socialism is not a political system. It is an economic system. Socialist countries can be totalitarian, monarchies, democracies, dictatorships, oligarchies, aristocracies, republics, plutocracies, or whatever. Gee, I wish you people would learn the difference. Socialism is an ECONOMIC system whereby the government controls the means of production and distribution of goods and services. That can happen under ANY form of government.
