> after all people didn't starve before Russia had modern farming equipment.
Yes, they did. You don't know your history or are deliberately ignoring parts of it.
Russia and the Russian Empire was always struggling to produce enough food due to the nature of its landscape. Barely any of it is suitable for farming.
This is the main reason Russia always tries to expand westward (that and its lack of warm-water ports for trade). It's simple self-preservation. I'm not excusing some or all of the horrible shit they've done to pursue this goal either, but it is understandable. The US did exactly the same when it swarmed over North America wiping out or subjugating every Native tribe it encountered.
The arable land in Russia is incredibly slim and was mostly situated on its western countries bordering Europe. Most of Russia and many of its satellite states during the USSR is and were unsuitable for farming.
On the subject of US/NATO trade embargoes, the US did a similar thing to Cuba and some South American states for decades for no good reason other than 'communism bad!'.
Trade embargoes used as a tool to fight an ideological war by weakening the target country's economy, thereby discrediting its economic model by artificially limiting supplies of grain and efficient farming equipment.
All they ended up doing was hurting the regular people who probably couldn't have cared less what system they were under. They were too busy trying to live their lives.
There was nothing in the Soviet system that prevented it from trading with the west from an ideological standpoint either. The refusal to trade came from the west; and the only reason trade with the west was hindered was because the US wanted to fight an ideological war by undermining its enemies economies.
The reality is, the so-called free-market champion that is the United States engages in market distortion to eliminate rivals all the time. The best example recently was the Iraq War. That was a response to Saddam Hussein's plan to stop trading oil in dollars and switch to Euros instead.
I feel like you are deliberately ignoring information that doesn't satisfy your world view.
I cannot help you with that.
