I'm suggesting europe take the 800 billion they're going to spend on deterrence and instead buy weapons for Ukraine today. This would degrade russias military sufficient to need to spend less on deterrence in the future. In no way is this supportive of russia.
As an example: If europe gave Ukraine enough cruise missiles to wipe out russias Tu 95 fleet that would be a permanent loss. They were built by the Soviet Union and rebuilding them would take a hundred years at least.
What europe fails to see is the massive ROI from supporting Ukraine today.
Deterrence is usually the reason why a category of nation-state aggression doesn't exist. Otherwise, the fact that we've never had a global nuclear war would be sufficient to prove that we don't need to deter a global nuclear war.
