"The nuclear debate in Washington is only about the past, about a notion of this nation as the better of only two options. It's as if the critics are wondering: why must we tinker with everything that made America once spectacular? Endless discussions about whether America is exceptional or not (and whether this president thinks we are or not) are preconditioned on a memory that equates the size of our nuclear arsenal with our own relevance. It is simplicity in its most perverse form. What makes us exceptional is our capacity to adapt to a world that has changed, not holding onto a world dynamic that ended long ago."
