No one ‘likes’ war, but it is sometimes a necessity. Sometimes standing up stops the war from happening... However, in this case, no one is going into the bear’s back yard, the bear is coming into our back yard (unless your analogy is reversed and you aren’t referring to the bear in this case as the Russians re the old Soviet Bear metaphor.)
No, I’m talking about the slumbering bear in the woods during hybernation - those things are awfully cranky when people mistakenly wake them!
