>>Please show me any country where communisms has ever been a success
Socialism or Communism? Big difference.
IMHO Switzerland shows a number of positive attributes, being fiercely capitalist while offering most socialist advantages of the Scandinavian nations... in fact of most other Western nations. It helps that the Swiss are very good at avoiding war on their own soil, or at all in fact.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
