Socialist Progressives

maybe one reason "socialist" countries have fallen might also be attributed to the MASSIVE opposition they faced from the worldwide dictatorship of capital, primarily represented by the United States of America. One was a cute cartoon that made the point starring Homer Simpson, but the other, IMO, was even more effective because it featured a Henry Kissinger quote about how the future of Chile couldn't be left to the Chilean people.

In spite of the fact that most socialist regimes have been internally flawed and deformed, it's difficult to say where they would have wound up if they hadn't faced serious opposition and undermining from the USA, militarily (overt and covert), economically, and politically from the moment they take office. They might have worked through their problems if not for the undermining. We'll never know.
