In his April 28 Washington Post column, David Ignatius said:

Beyond the carnage the Ukraine war has produced on the ground, it has forced military planners to think anew about the risks of nuclear war. For the Pentagon, that means extra urgency in developing a new generation of doomsday weapons that could maintain deterrence.

The Pentagon budget request for fiscal 2023, framed in the shadow of the Ukraine confrontation, has a stronger strategic-weapons emphasis, including a new-generation intercontinental ballistic missile (ICBM) known as the Sentinel, a new B-21 manned bomber, and an exotic mix of drones and manned fighters known as Next Generation Air Dominance, or NGAD.
