You're showing statues of Lenin in countries in which the Dictatorship of the Proletariat failed to cede power to the working class and establish a socialist economic structure.

When Lenin took power, Russia had nothing. It was in the middle of WW1, there were regular famines, almost everyone was illiterate, and it was in no condition to establish a socialist economic plan. So, Lenin created a temporary economic model called The Dictatorship of the Proletariat. This is a centrally planned economy designed to rapidly develop infrastructure and industry in a country that has none. Lenin was already ceding power to the worker's councils when he died. Stalin decided he liked The Dictatorship of the Proletariat and did not cede power back to the worker's councils.

Those countries never experienced Communism. They never even experienced socialism. They destroyed those statues because they hated The Dictatorship of the Proletariat. Living in a system designed for a short temporary economic boom for decades is no fun.
