"a modern nuclear infrastructure was essential for facilitating reductions in the arsenal while sustaining deterrence"

"I really want to be clear about it. Modular and that kind of thing-- modernizing effectively our nuclear weapons arsenal is essential."

"Will DOD take a proactive role, using the NWC, to determine the feasibility of the modular approach by this summer?"

"The DDPR concluded that the 'alliance's nuclear force posture currently meets the criteria for an effective deterrence and defence posture.'"
