The nukes just laying around in stockpiles are mostly in the 100-800kT range. You could use nukes that would otherwise need refurbishment (exploding old stockpiles and producing new stock instead of refurbishing old stock), or maybe even spin it as a disarmament treaty where the method of disposal are underground explosions for carbon sequestration. Or use it as an opportunity to use old nukes for a good purpose when you want to switch to a newer model (instead of needing facilities to disassemble them)
