The value of nuclear weapons is inherent in their power. It has nothing to do with how the United States makes them look. That must mean that nukes are not that important anymore. No need for us to have them then. Let's make plowshares.
Nonproliferation is a very good idea.
But there is a problem. It is not very fair. Unfortunately, there is no cure for this problem. It is absurd to believe that we cure it by pretending nuclear weapons don't matter and letting ours get rusty and unreliable. Neglecting the maintenance of the arsenal either has no effect, in which case it is a sham.
