We were not talking of generic socialism, but of marxist "communism", the one that prescribes revolutions in all states and, after these revolutions, in each state, "a transitional phase [that] would be needed in which the working class would have to impose its political will on the capitalist class, precisely a class dictatorship", i.e. a "dictatorship of the proletariat". AFAIK this only applies, among the examples you made, to USSR, China and Cuba. Maybe also to North Korea and Vietnam, but i don't know for sure. The netherlands have a form of social democracy with welfare and lots of capitalism in the economy. The kurds started with marxist aims and then integrated some elements of Murray Boockchin's municipal communalism into it. I don't know how the zapatistas may be defined, however i guess they do not want to replace the current state with a "dictatorship of the proletariat", but are oriented towards a sort of territorial communalism with no central government.
