Hahaha :ffsparr:. You honestly think in Crimea and Eastern Ukraine there are no Russian troops? Did the 'militias' just appear out of the ground?! I read some rubbish on NSC but that wins. it. :shootself
The demographic argument doesn't address the point, Putin would not have wandered into Ukraine if Kiev had Nuclear Weapons, they would have said 'you invade Ukraine then we use the bomb'.
In comparison to Ukraine, who gave them back to Russia in return for Ukrainian territorial integrity in Crimea. THAT WENT WELL.
If Ukraine had nuclear weapons, there is zero chance Putin would have invaded.
