Hypergols are both volatile and toxic, and do degrade markedly over time compared to solids, room temperature liquids like RP1/Peroxide could work but also degrade over time and as multiple Russian nuclear subs discovered, storage of liquid HTP under pressure can be quite dangerous, and cryos are off the table because they need a whole logistical chain and significant continuous power generation to remain in a usable state.
So while solids are shitty in ISP, and don't lend themselves particularly well to throttling, or moment-to-moment control, they can still put a nuclear weapon within less than a kilometer of the target where it will have maximum effect, and can be stored for long periods of time with zero maintenance.
That's all that's necessary for a nuke, although I must admit, it would be cool to be able to drop a warhead within +/-5m of the target, the nature of nuclear weapons doesn't require that level of accuracy at pretty much any scale, even the smallest possible nuke imaginable wouldn't need such a level of precision.
