It scares me that anyone could come to this conclusion. Are you so clueless about the unimaginable, unprecedented suffering and death that such a conflict would bring, or does your emotional attachment prevent any rational assessment? There is no reality where WW3 and "not necessarily a bad thing" belong in the same sentence.
It's a good thing to punish territorial aggression, but there can be no doubt that WW3 is the worst outcome for everyone.
Is this a threat?
