The "you can't blame economic failure in socialist countries on outside subversion" crowd is forever wrecked. Obviously you can't entirely blame it on outside subversion but this is direct evidence that the CIA, and probably other intel orgs in the USA, have worked to consciously destroy socialist countries economically for decades. If a liberal ever starts asking you why you always blame the intel community for overthrowing Leftist countries show them this shit
I know you are joking but thus is actually not so far from the truth. Soviet ruble was backed by gold and one of the most stable currencies in the world, so the US and the UK decided to only demand grain in exchange for tools which the Soviets needed for industrialization. They deliberately tried to starve them out.
