What info do you have on adversarial capabilities beyond speculation and belief about their recent military expenditures?
Do you believe that the USA hasn’t considered your scenario already and put plans into place? Do you believe civilians would know the full extent of our nuclear capabilities?
Why do you believe China and Russia are possibly planning to disarm USA’s triad, and why do you believe they’d have the intelligence to do so? Something about leaks, the nsa, whistleblowers.. is there a connection here? Just speculating based on your notion that USA may be getting ganged up on by China and Russia.
Frankly your line of thought is valuable and worth exploring, and I’d like to see what info can be put on the table to explore your ideas further.
