Putin has offered to negotiate on and off but always under terms that are stupid. Usually some variation of “If the West surrenders Ukraine to Russia we promise to stop until our army is rebuilt”. He is just offering to negotiate so he can say he offered, not because he has any real plans to negotiate.
By Putin’s refusal to use the necessary force to deal with the dangerous situation and by continuing to insist that the conflict is nothing but a limited operation
Putin has already committed most of Russia’s entire military. The only step up would be general declaration of war, moving all industry to military production and universal conscription.
Putin has a few months to end Ukraine’s existence, a country that never existed until Washington created it,
Washington had nothing to do with Ukraine’s creation. Russia and Ukraine have been feuding through recorded history.
