> The war started because of NATO screwing around in Ukraine's politics and trying to set up NATO on Russia's border.

That sounds like an attempt to rewrite history. Ukraine's prospect of becoming a member of NATO was completely buried since 2008, and the intention to join NATO was resurrected only after Russia invaded Ukraine in 2014. To this day, the interest of other members to accept Ukraine into NATO remains lukewarm and no meaningful progress has been made in this direction.

The war started because Russia couldn't stomach that Ukraine was on the verge of signing a major trade deal with the EU that would've opened up the EU market for Ukraine, and Russia, facing its vaning influence over Ukraine, decided to invade and subjugate Ukrainians through violence, as it had nothing else to offer.
