Question 1

Nuclear war decisions are hyper‑centralized and time‑compressed.

Accepted Answer

In the U.S., the president has sole authority to launch nuclear weapons and does not need approval from Congress, the Secretary of Defense, or the Joint Chiefs. This structure exists because an intercontinental ballistic missile (ICBM) can reach the U.S. in roughly 30 minutes, leaving about six minutes for the president to choose a response from pre‑planned strike options in the so‑called “black book” stored in the nuclear “football.” There is no time for deliberative debate once launch is detected.

Question 2

Modern thermonuclear weapons are vastly more powerful and more numerous than WWII bombs.

Accepted Answer

The Hiroshima bomb was a ~15‑kiloton atomic device the size of a small elephant, delivered by aircraft. Today’s thermonuclear (hydrogen) bombs use an atomic bomb as a trigger inside a larger weapon, producing orders of magnitude more destructive yield, miniaturized to fit atop missiles. The U.S. and Russia each have around 1,700 deployed strategic warheads ready to launch, plus thousands more in reserve; nine nations in total possess nuclear weapons, many currently in direct or proxy conflict.

Question 3

Deterrence is fragile; small errors or “mad king” decisions can end civilization.

Accepted Answer

Jacobsen details near‑misses, such as a 1980s incident when a training VHS tape simulating a Soviet attack was mistakenly fed into a live warning system, briefly convincing U.S. officials that missiles were inbound. She also describes how a single submarine‑launched missile—whose origin cannot be tracked like a land‑based ICBM—could trigger misinterpretation and uncontrolled escalation. Experts, including the UN Secretary‑General, now warn we are “one misunderstanding, one miscalculation” away from nuclear Armageddon.

Question 4

Missile defense cannot realistically stop a large‑scale nuclear attack.

Accepted Answer

The U.S. currently fields only 44 ground‑based interceptor missiles against long‑range threats, versus roughly 1,700 deployed Russian warheads, many of which are MIRVed (multiple warheads plus decoys per missile). Intercepting a warhead is like “trying to shoot a bullet with a bullet” at combined speeds over 30,000 mph, in space, under crisis conditions; even in curated tests, success rates hover around 40–55%. In a real saturation attack, missile defense would be quickly overwhelmed.

Question 5

A plausible U.S.–Russia exchange would destroy cities in minutes and starve billions within years.

Accepted Answer

In Jacobsen’s scenario, one rogue launch (e.g., from North Korea) and subsequent misinterpretation leads Russia to fire a full salvo at the U.S., and vice versa. A single 1‑megaton bomb vaporizes everything in a multi‑mile radius at ~180 million degrees, generates hurricane‑force blast waves, mega‑fires of 100+ square miles, and mass radiation poisoning. Climate models show resulting soot would trigger nuclear winter, collapsing global agriculture; recent Nature‑based work suggests roughly five billion people could die from starvation.
