Erik Baker summarizes Willis' concept of "bomb power" succinctly in The Baffler:

the way that the very existence of the United States’ nuclear arsenal fundamentally constrains the possibility of exercising democratic oversight of the nation’s military. The power to annihilate all human civilization cannot sanely be disposed of by popular vote. The bomb is a weapon suited only to a benevolent dictator, and that is how the United States came to envision the presidency in the nuclear age—culturally, politically, and even legally. Autocracy, of course, was easier to produce than benevolence. The bomb demands secrecy; secrecy demands lying; and lying demands lawlessness.
