Wishing something to be true doesnt make it so. I havent seen any credible assessments that Russia’s strategic nuclear arsenal is so bad that it would be more that 90% non-functional. That’s an insane level of broken that there is just no reason to assume it.
Put another way, way more than 10% of their tanks, planes, artillery and tactical ballistic missiles work, why would you assume that their strategic nukes are significantly worse?
All of which isnt to say we should cower before Putin’s obviously empty nuclear threat, let Ukraine release the storm shadows! But to go from there to lol dumb Russians cant fire a single ICBM is just not credible.
She did exactly what you suggested, except you havent heard about it because it doesnt generate media coverage, this does.
