The west doesn’t want Ukraine to defeat Nazi invaders from Russia. They want cheap Russian energy to finance the loopy climate change agenda, etc. It’s similar to WW2 actually with Hitler and Stalin in confederation. Follow the money as they say and every day hundreds of millions of dollars pours into Russia from Soros HQ EU.
The threat of competition from Ukraine is why Russia siezed Crimea and formented the rebellion in the east in 2014.
