We are currently closer to nuclear Armageddon than at any point since the Cuban Missile Crisis. While many prefer to live under the comforting illusion that such a conflict could never happen, the reality is that nine nations now possess these world-ending weapons, standing on a "razor’s edge" of potential catastrophe.
The Prepared Citizen breaks down one threat every week, and the exact steps to prepare for it.
Phase I: Before — The Six-Minute Warning
The timeline of a nuclear exchange is measured not in days or weeks, but in seconds and minutes. The moment a missile is launched from a silo or a road-mobile launcher, the United States’ SBIRS (Space-Based Infrared System) satellites detect the heat plume of the rocket exhaust in less than a second.
This triggers a "five-alarm fire" alert. Within roughly six minutes of a confirmed launch, the President must be briefed. In the United States, the President has sole launch authority, meaning they do not need to consult anyone else to order a counterstrike. During this frantic window, the President would be moved to a classified bunker like Raven Rock, while the "Nuclear Football", a suitcase containing the "Black Book" of strike options is opened.
The options are grim, often described as a "Denny’s menu" of targets and predicted death tolls. Once the President gives the order for ICBMs to launch, they cannot be recalled.
Phase II: During — The 1,600 Seconds to Annihilation
A nuclear strike consists of three distinct phases:
Boost Phase (0–5 minutes): The missile clears the atmosphere.
Midcourse Phase (approx. 20 minutes): The warhead travels through space at 15,000 miles per hour.
Terminal Phase (last 100 seconds): The warhead re-enters the atmosphere and detonates.
If you are near a detonation, the first thing you would experience is a flash of light brighter and hotter than the sun, which can vaporize those at ground zero and cause life-threatening burns dozens of miles away. This is followed by a radiation flash of gamma rays and beta particles.
Finally, a supersonic shockwave arrives, leveling buildings and turning glass into lethal shrapnel. While "duck and cover" may seem futile, it is intended to provide a slight chance of survival for those in the "buffer zone" far from the center, protecting them from collapsing ceilings and breaking windows.

Phase III: After — The Nuclear Winter
The immediate blast is only the beginning. The resulting firestorms would pull soot and smoke high into the stratosphere, forming pyrocumulonimbus clouds. Unlike normal smoke, this soot would rise above the level of rain clouds, meaning it could stay in the atmosphere for a decade.
This creates a Nuclear Winter, where sunlight is blocked and global temperatures plummet below freezing. Even a "small" exchange between India and Pakistan could send enough soot into the sky to kill two billion people through starvation as global agriculture collapses. A full-scale war between superpowers could kill five billion people, ending modern civilization as we know it.
Is There Any Hope?
While the Northern Hemisphere would be devastated, some nations in the Southern Hemisphere, such as Australia, New Zealand, and Argentina, might endure because the nuclear winter there would be milder and they have enough livestock to potentially feed their populations.
However, the ultimate lesson from those who study these weapons is that luck is not a strategy. As Albert Einstein famously remarked, he did not know how World War III would be fought, but World War IV would be fought with "sticks and stones". In the end, the enemy is not any specific nation, but the nuclear weapons themselves.
