Try to do some reasoning here. The USA is the most violent country on the planet, responsible for more deaths than any other country in the modern era. The only country to use nukes on the battlefield and they used them kill civilians while negotiating a surrender. The country that enslaves the largest number of their own people for profit. The country that maintains fascism throughout the world.

Russia isn't allowed to do this because the USA is worse. Russia has no other choice but to push back the violent fascist nuclear military expansion of the USA because of it doesn't the USA will have Russia in a kettle, surrounded by nuclear first strike capabilities. The last time the USA had even a modicum of influence over Russia it killed millions of Russians through economics alone. If the USA finally got NATO nuclear capabilities into Ukraine the way it's been planning to do for 30 years against the protests of literally every sane person and also of Russian peace negotiations and national security concerns, it would be capable and has shown willing it would kill millions of Russians to balkanize it and turn it into a vast US military base, strip mine, and labor camp.

The reality is that proxy wars kill tons of people, and the responsibility lies with the proxy master. In this case, Ukraine is the USA's proxy in a war with Russia. The USA causes this war. Without the USA's actions, Russia would have never needed to take Crimea, would have never needed to send troops to protect the Donbass, and would have never needed to launch this SMO. All of these innocent deaths are deaths in a proxy war launched by the USA.

What's insane is believing that the USA is "bad" but that everyone else is worse. What's insane is believing that the USA killing millions of people and administration genocides continuously for a century is going to be resolved without war. The body count in Ukraine is on the hands of the USA and is still so much smaller than the rest of the USA's body count. Ending US hegemony is the only way to save the lives of Innocents.
