The US also hasn't tested since 1992. Given the situation with B-2 heat exchangers, F-22 spare parts and FOGBANK, I would not be interested in betting large amounts of money that American nuclear weapons are fully functional either.
Interestingly enough, both the US and Russia routinely test fire ICBMs. So we know the rockets work, but not the warheads.
A very awkward exchange would be if Putin goes nuts and orders a first strike, we do a "use em or lose em" ICBM launch, and all the warheads fizzle over their intended targets. What then? Awkward coughing and shuffling of feet? Roll the tanks for a full-scale war in Europe? If the nuclear umbrella truly was the only thing preventing direct Great Power conflict, then do we shrug and institute 20th century-style mass conscription and blow the dust off all the century old war stockpiles?

Putin is not crazy, he is acting rationally from his perspective (though it may be hard to understand). My suspicion is that the reports of him having cancer are correct, and the Ukraine invasion was a way to bolster and secure his position in the face of doubt caused by the cancer.
Although I (think I) know what you mean, the idea of starting a war, killing thousands of people, destroying cities and destroying the Russian economy all to avoid looking weak due to cancer... well, it certainty sounds pretty fucking crazy to me.
I think Putin believed that this would be a quick victory, capturing the Eastern oblasts, and either negotiating a settlement with the Ukrainians, or conquering the country and installing a puppet regime. This is what most analysts seem to have expected, and the fierce Ukrainian resistance is what's forced the West to implement strong sanctions.
I think “rational” and “crazy” are not incompatible; to me, a lack of empathy is a type of crazy, and yet I also think people who lack empathy can make rational or irrational decisions about how to reach their goals.
I’m not sure I’d count Putin as rational even given a lack of empathy, given what seems to happen to successful Russian generals even before this war.
Suicide is a terminal disease. Psychopathy is a chronic condition. You could suffer from both, but we've never seen suicidal tendencies from Putin.
