This is a silly idea.

The Russians are already exterminating children, hospital patients, people trying to escape and people waiting in line to buy bread. I don't think they would respond to this any differently.

I’m sure the idea is well-intentioned, but this type of naive scheme would be seen by the Russians as further proof of Western weakness and childishness, and an invitation to more aggression. They see the West as a dying tree whose fruit is ripe for the taking.

I think the Russians would fire on them without hesitation.

I am deliberating your rationale. I sense you are mistaken when thinking Putin wouldn’t “dare” anything.. including a nuclear strike if he deemed it necessary.

It pleases Putin to order the slaughter of anybody and everybody that he perceives as standing in his way. This includes unarmed civilians, children and babies. He is fixated with establishing his personal rule over subject peoples as a way of counteracting his own catastrophic insecurities of personality.

He is a mass murderer pure and simple.

Many are already doing that. And Putin is already firing on them.

Bet you a dollar?

Putin's forces regularly fire on civilians, whether in a hospital, theater basement, breadlines, etc. Recall that Russian forces aided Syria in gassing civilian neighborhoods with Sarin.

I'm not sure Putin wouldn't fire on them. They would be sitting ducks. He enjoys slaughtering people, then sitting back and daring the world to do something about it. It would be a convenience for him.
