Russia warns for decades about NATO expansion, and that Ukraine is absolutely a red line for them.
I couldn’t agree more. Russia can justify the invasion (right or wrong). If DT was president, Russia would not have invaded Ukraine; other than that, as long as Ukraine keeps building friends with Russia’s enemies instead of taking sides with Russia, Russian aggression is inevitable. Also, Russia wants Ukraine short of a puppet Ukraine. The proximate cause of the invasion is Ukraine taking sides with Russia’s enemies and not submitting to Russia.
