Russia is a house. Ukraine is a house. USA is a house. Russia gave up on their project of building a workers' state and attempted to join the liberal capitalist world dominated by the USA. The USA sent economists to Russia's house. The economic reforms killed as many people as though Russia had been invaded.

Still, Russia wanted to join the USA's economic dominance. But, the USA had built a transnational nuclear military specifically to counter the Russian military. They staffed it with officers from the Third Reich. They built Operation Gladio, Operation Paperclip, and Operation Aerodynamic. These operations grabbed the most violent bullies in the world and protected them, put them into houses neighboring Russia's house, and took the one's already there and gave them all weapons and training.

Still, Russia wanted to join the USA's economic dominance. They asked the USA to not expand NATO to its borders, sorry, to it's front lawn because that would be impossible for Russia to defend against. Russia was run by a stooge that the USA controlled. That stooge hand-picked Putin under USA guidance. Putin continued attempting to appease the USA despite it's bullying. Russia was trying to join NATO to ensure mutual security concerns could be discussed in committee instead of on the battle field.

The USA finally rejected Russia explicitly and kept training and arming bullies. Every time the HOA tried to ban the practice of glorifying the Nazi bullies in the neighborhood, the USA vetoed it.

The USA kept building more and more gangs and they kept building more supply lines and more weapons and more capabilities and finally tried to install those capabilities on Russia's front lawn. During this time, Russia escalated its readiness and it even took military action to prove that if the gangs kept coming they would react.

The gangs kept coming.

Russia reacted.

Your story has absolutely ZERO relevance to the actual history of the situation.
