By “succeed” you mean the 1000s of countrymen and women that were slaughtered to silence by the tyrannical leaders’ armies because they were an actual threat to their grip on the people. The “success” that so many outsiders take as fact is nothing but cleverly crafted lies to make communism and socialism seem better than it actually is. The REAL truth is told by the citizens that successfully fled said countries and fled to America and other free countries. Listen to their stories and the things they experienced. THAT is the truth of what goes on in the countries.
