Without knowing the finer details, my assumption would be that it's some kind of risk/reward tradeoff.

Ok the nuclear risk is higher, but causing chaos in nuclear security could create opportunities like giving Trump or Musk more direct access to the nukes or removing people who might have prevented them from using them, thereby granting them more personal leverage. This would be in keeping with the Project 2025 aligned executive orders and such.

There might even be commercial opportunities for Musk: "oh well the state management of nuclear security was super inefficient, ApocalypseX will do it"

Remember disaster capitalism is a thing.
