I don't have a good handle on this apparently you need to research the very definition of socialism because all those countries are capitalist systems. Private ownership of the means of production, distribution, and exchange exist in those countries rendering them capitalist. Venezuela is true socialism all means of production, distribution, and exchange are state owned. The people of Venezuela are literally starving to death right now even eating zoo animals.
Plus you never answered the question how do you expect to impose this socialist utopian society without the use of force? You cannot. So you are openly advocating the use of force aka violence to achieve this.
I could go on about where it hasn't worked (Venezuela) the most current catastrophe. But I know the Mo of you . You will just claim what ever example I give to not be "true socialism".
