a nuclear warhead going off in a silo, especially where the United States and the old Soviet Union put most silos, is a meh.
It's not a meh, it's a myth. The physics package can only be triggered after a fairly complex set of conditions have been fulfilled, starting with launch authorisation, a period of high acceleration, a period of zero-G (long enough for the warhead to have moved outside the continental US), re-entry heat, and so on. And unlike any number of Hollywood movies, this isn't something you can bypass by uploading a hotfix, it's fixed-function stuff that can't be changed.
Another thing about these gee-whiz national-lab designs is that they've been coming up with them since the 1980s (and probably earlier than that, I wasn't around then). None of them ever get used. They eventually find their way into civilian applications (things like MEMs, PUFs) years or even decades after the national labs come up with them, but they're never used for arms control due to a mix of massive inertia, difficulty in turning a proof-of-concept into a fieldable item, and the fact that deploying them typically requires renegotiating international treaties.
(This is a very abbreviated description of something that'd take a book to cover).
