The thing is, he is the one much better equipped to handle it. Ukraine is important to him and it is just side-story for US, not any kind of primary concern.
You seem to be assuming that NATO is "better equipped" - but how would they be? You aren't proposing anything that haven't been proposed before; every potential weakness have been long investigated on both sides and either pushed or cut already.
You thinking that he can be pressured through family threats is silly.
If he decides to "go into Ukraine" there is no other outcome then Ukrainian defeat; but at the moment it is primarily Ukrainian fearmongering.
I would hope you want it to stay that way?
Or do you want him to go in so that you would finally have "good reasons" to crush him?
If you would make credible threats to his family - even in "things stashed for future" kind, why do you think he would instantly fold rather then just make another stash you cannot reach?But I never once threatened anyone in that post personally.
Not you personally; those who would act on such plans.But if you are trying to elude that Putin would track me down personally and kill me because I suggested what the US and NATO should do even though I have zero power and authority, you have even less respect for Putin than I do as no one in their right mind thinks he got to where he is today being THAT petty.
