As crazy militant as Russia is being I don't think they'd bother flying in such a massive bomb. That is if current nuclear trends even recognizes air-dropping a bomb anymore, and not just using ICBMs.

They do. Airdropped bombs are still a component of the modern nuclear triad - but ICBMs and SLBMs are expected to do most of the heavy lifting. A nuclear bomber now would carry cruise missiles and numerous small bombs.
