Oh, I thought Russia just wanted to protect the Sudeten? That's what I usually hear :) Nato has nothing to do with it. I don't know what stoltenberg said and how it was taken out of context, but NATO is an organisation to which countries apply. Nobody is forcing them to join (except the threat of Russian invasion).

Ukraine is not that small and Ukraine would fight if it gets the weapons or not,because they are fighting for themselves. Likely less will die when they have something to fight with.

The actual evidence shows that Ukraine is losing far less people than Russia. One of the most evident proofs is the oryx report of lost hardware. It had it's flaws but I think it's very relevant. The leaked US report about two months ago has Ukraine at about 70k dead and Russia at 120k.
