I've said repeatedly that no one will ever give up nuclear weapons again after Ukraine - and that salvaging any hope of nuclear proliferation control was one of the many reasons Russia needs to lose this war.
Putin knows this, of course, but obviously doesn't care. Now they (and China) have functionally ended sanctions against North Korea over its nuclear weapons programme, and it strikes me as rather unlikely they'd tolerate a new such regime against any other dictatorial state trying to insure its longevity through nuclear weapons.
