Exact same? Nobody can invade a nuclear power. Nuclear power on the other hand can invade and obliterate however they like a non-nuclear power with no alliance with nuclear power.

So yeah. If Ukraine didn't want to get destroyed and people killed, maybe they shouldn't have pulled a nazi and start shelling ethnic russian regions(Ukrainian civilians) provoking Russia to invade Ukraine for the US funding lol. I mean like why would you want Russia to fuck you up while being a corrupt poor country that's been selling it's soviet weapons stock in every other conflict and actually having millions of Ukrainians emigrating to Russia over decades lol.
