there is no reason to panic. if Putin uses nuclear weapons, he will use tactical nuclear weapons on the territory of Ukraine to disable the equipment that controls NATO weapons for precision strikes. the world will not receive such radioactive contamination as in the Chernobyl accident.
You're falling for the party line again.
He will use nukes, but I suspect not on Ukraine. If he does that, Biden's gloves are off. He said so. I believe his exact words were "catastrophic consequences for Russia."
I suspect Pooptin will first send about another 100 000 young Russian men to their deaths, topped up by about 50 000 more Ukrainian/international volunteer soldiers and another 30 000 to 50 000 Ukrainian civilians. The war will be stuck at a stalemate for over a year, or maybe 4 or 5, as MissC said. Puppet government buildings in Kherson and other occupied territories will continue to get pelted with malatov cocktails by the residents, and puppet mayors will continue to get assassinated with car bombs. The UN will not accept the results of the phony referendums, and the residents will not, either.
Pooptin will eventually die like nearly every other Russian leader, leaving his country and several others in ashes bc he associates peace with weakness and wants history to remember him as a badass.
If he's not assassinated by his own people, and instead dies in his bed of w/e illness he's supposed to have, he will likely nuke Britain or the US. Just to be a douche and say that he did it.
Any nuclear explosions that happen in Ukraine will likely be bc the Ruzzian army is so fond of camping out in the shadow of nuclear power plants like Chernobyl and Zaporizhzhia. I suspect the Ruzzians will aim their nukes at one or both power plants, and blame the disaster on the Ukrainians, Josef Goebbels style.
Then they will nuke England and the US. Or rather, they'll nuke the North Sea, and cause a tidal wave over Britain. Then they'll nuke the Americans.
Then the Americans will respond with nukes of their own, then more of their enemies (NK, Iran, etc.)
Then those of us who are not affluent enough to be able to escape to a well stocked fallout shelter will all die in the nuclear winter.
No big loss, imo. Personally, I think Thanos was right :P
