I think they are stating the odds of the federal government actually allowing secession to go through would be...minimal at best, given these assets in the state.
Bingo. 100-200 physics packages go through the facility annually, and if you think Uncle Sam got mad when someone touched his boats, try touching his nukes.
Every single piece of nuclear ordinance goes through that area. There are likely hundreds of near functional nuclear warheads under maintenance at any moment.
They're a larger nuclear power than China, England, France, or any country other than Russia and the US. What they don't have are delivery systems.
If they have the physics package they don't need the codes. Those codes to deter a grunt or rogue commander. A place like Texas can easily make bombs out of the physics packages
I’d imagine that they have everything they need to make devices without a PAL.
I believe you need a code in order to disassemble a PAL protected device without it self destructing, presumably these disassembly codes are different from the arming codes.
