Questions & Answers

Q: What is launch-on-warning and how does it impact nuclear war decision-making?

Launch-on-warning is a policy where the United States would launch nuclear weapons in response to an incoming nuclear attack, even before the attack hits, to prevent damage. The president has approximately six minutes to make the decision to launch once a warning is received.

Q: How does sole presidential authority play a role in nuclear war decision-making?

Sole presidential authority means that the president of the United States is the only person who can make the decision to launch nuclear weapons. This concept is to ensure quick decision-making during a nuclear war scenario.

Q: What are the different ways a nuclear war could start?

Nuclear war could start from an intentional attack, miscommunication or misinterpretation of signals, technical errors, or an accidental launch. For example, the launch-on-warning policy could be triggered by a false alarm, leading to a devastating response.

Q: How effective are interceptors against incoming nuclear warheads?

The United States has limited interceptor capabilities, with only 44 interceptors that are around 50% effective. If multiple nuclear warheads were inbound, interceptors would not be able to stop all of them, leading to significant destruction.
