Isn't there some sort of moratorium of developing new? Or is it just a moratorium on testing? Agree with you, cost of new (and reliability of new) favors shifting to new.
Thanks for the corrections on size of stockpile. My general point was that the issue is probably more complex than what Trump has in his head right now. The size of the stockpile is a strategic calculation, and tough of its own right.
I know that we don’t do live nuclear tests anymore, new development is all done through simulations. Unsure if there is a stoppage on newer development.
