The US should, if it had any balls or was worthy of trust, declare that any nuclear attack on ukraine will be seen as a war declaration to the US.

My understanding is that a nuclear attack against Ukraine puts the Budapest Memorandum in play. The effect will be similar, in that we'll be more or less compelled to join the war on Ukraine's side.

If we fail to do that, then good luck with any future nonproliferation efforts that involve promises from the "good guys."

Oddly enough China agreed to protect Ukraine in the event of a nuclear strike.

China aims at becoming/remaining the world #1 economic superpower; Europe's GDP being 10 times the Russian one suggested them to be more pragmatic.
