Absolutely not - if only because what you do to one, becomes do-able to another.
Too, it really would be the start of WWIII. Even the attempt is arguably an act of war.
If it happens, it'll happen from within Russia, but that's not automatically going to be a good thing. Whatever prompted Putin to go for the Ukraine, he's a very experienced, long term leader who knows how the game is played very well.
Whoever replaces him, might not be, and its even odds that they'll be more hostile and more trigger happy. There's a hard earned history of 'better the devil you know' when it comes to regime change.
Besides, ultimately, Russia walked itself out of its isolationist, nuclear-threatening political stance once before; it can do so again, should it choose, and there's every reason to think that it will. There's a fair degree of evidence that the population aren't happy with any of this, and as winter drags on, and living conditions toughen and his implemented draft bites, that sentiment is likely to grow.
