How can we stand before the world and tell countries that aspire to become nuclear powers to abandon their weapons programs when we’re expanding ours? The idea of the nuclear haves telling the nuclear have nots to remain have nots has always chafed, but when we’re moving away from drawing down our arsenal and actively pursuing the development of new kinds of nuclear weapons, we ought to just shut up or simply resort to threatening countries that are trying to go nuclear, because that’s the only authority we have. As far as I’m concerned, the need for “bunker busting bombs” is completely a figment of the imagination of people who just love to pursue bigger and better weapons. And even if they were desperately needed, I would still think that the cost of expanding our nuclear arsenal wouldn’t be worth it.
