It's foolish. Why would Russia use a fucking nuke? That'd be a historic admission of WEAKNESS when on every measure Russia is winning the war.

All Russia has to do to 'make a statement' is to use a hypersonic missile and hit a NATO base. Russia has Avangard hypersonic reentry vehicles that go SO FAST that when they hit they explode with a Hiroshima sized explosion but use a nonnuclear explosion.

So why use a nuke if you have weapons like that in your arsenal?
