I don't dispute that the country has been run badly but calling states that do these things communist makes almost every state communist.
The nationalization referred to in Venezuela, is someone invests their own resources in building something, legally with the approval of the government. After they have built it, the government comes with people with guns, and says, "this belongs to us now" and either the owners go away, or go to jail, or get shot. Is that what they do in Norway? Do you think smart, capable people with access to capital want to work in Venezuela? Or maybe all those people left and provide their services to other countries.
And by the way, this Venezuelan kind of nationalization sounds too me like the kind that Marx was advocating, it's real socialism too.
For examples of already-existing companies being nationalised, see RBS in the UK, or Cardiff Airport in wales. After the 9/11 attacks in the US, all airport security firms were forcibly nationalised.
If you are claiming that the definition of socialist requires it to be done with guns instead of money, I don't know what to say. However be aware that if somebody did create an oil company in norway against the law then I imagine that some nice people from the government would have to come and ask them not to. If they refused despite that - they may actually have to make use of the state monopoly of violence.
I don't think most people here have a problem with a democratic country with socialist leanings, which maintain a largely market economy. People have a problem with populist leaders who promise to enrich the poor by forcefully taking the means of production away from "capitalist pigs" and using the wealthy and the West as a scapegoat for all their problems. No one complains about Sweden and Norway, but the propaganda that goes around in Latin America is the more violent kind. And I don't see how that doesn't fall under the umbrella of socialism.
