I did not mean to make it right, please don't get me wrong. What I meant is that it's obviously wrong for anyone to invade other country who are independent. But for strategic interests world leaders are doing is from the beginning.
There isn't really any plausible strategic interest for Russia (as in Russian people, or Russian Federation; not the current clown dictator) to make Ukraine an impoverished, oppressed, resentful nation by attempting to invade it. It's just madman's dream to turn history back. This never works. And the Soviet history is horrid. No sane person wants a repeat of that.
Lecturing Ukrainians to stay neutral is no different than telling them to join Russia. They should treat any such "advice" like they treated that Russian warship.
