A 'nuclear football' briefcase always accompanies the president

A primer on the president's nuclear football

During the Cold War, the United States and the USSR were forced to prepare for a nuclear strike at a moment's notice, leading to a new innovation: the so-called "football" (known as the chemodanchik in Russia), a bag containing nuclear strike plans, authentication codes, and likely a communication device, which attended the country's leader wherever they went. This easy-to-read piece breaks down the history and lore around the high-stakes quirk in nuclear governance.

The president has the sole authority to call for a nuclear strike

Under current US policy, the president alone can order the use of atomic weapons at any time without requiring prior approval from Congress—a power rooted in the president's role as commander in chief.

Go inside Air Force One

Air Force One is the official aircraft used to transport the US president, serving as both a mobile office and command center. Over the decades, its technology, security, and symbolism have evolved—from Roosevelt's early prop planes to today's highly advanced Boeing jets.

There is a secretive bomb-proof bunker located under the White House

Built in 1942 during World War II, the Presidential Emergency Operations Center lies beneath the East Wing. Designed to protect the president during air raids—and later nuclear threats—it remains a top-secret command site used during crises like 9/11.

This video breaks down how the motorcade—anchored by the armored limousine known as "the Beast"—operates as a mobile security network. An animated simulation shows how agents and vehicles respond to potential attacks to keep the president safe in transit.

Einstein warned the president that splitting atoms could lead to powerful bombs

In a 1939 letter to Franklin D. Roosevelt, Albert Einstein explained that nuclear fission could produce immense energy—and devastating weapons. The warning helped spur the Manhattan Project, a role Einstein later deeply regretted.

The National Security Council advises the president on foreign policy and national defense

Created in 1947, the NSC coordinates military, diplomatic, and intelligence policy matters. Chaired by the president, it includes key Cabinet officials and senior advisers who shape American responses to global crises and security threats.

The alliance operates under a "flexible response" doctrine—that is, proportionality

NATO countries' main deterrent against aggression is their ability to respond with nuclear weapons. This video from "The Infographics Show" outlines the purpose of this nuclear arsenal, NATO’s strategy to prevent attacks, and its plans in the event of escalation toward nuclear war.

Ten lesser-known duties of the US president

The president of the United States is one of the most powerful positions in the world, but what exactly do they oversee? In addition to the obvious tasks of commanding the military, signing laws, and shaping national policy, this article highlights the lesser-known responsibilities of the American president. Naming national monuments and managing the White House beehive are just a few of the jobs you may be surprised to learn about.

A 'designated survivor' stays away from the State of the Union to ensure continuity of government

During major events like the State of the Union, one Cabinet member is kept at a secure location. This "designated survivor" would assume the presidency if a catastrophe eliminated those higher in the line of succession.

An NSA analyst helped avert nuclear war during the Cuban Missile Crisis

In October 1962, NSA cryptographer Juanita Moody headed analysis of U‑2 surveillance data and urgently produced intelligence on Soviet missile deployments in Cuba. Her reports drove high-level US decision-making, and were critical to avoiding nuclear war during the Cuban Missile Crisis.

Spikes in pizza orders near US government buildings are thought to be signs of international crises

Theorists have long believed that sudden increases in pizza deliveries near the Pentagon signal a major event is about to occur. Historical examples include the CIA ordering 21 pizzas the day before the beginning of the Gulf War, and another surge of deliveries before former President Bill Clinton's impeachment hearings. Citizens have since begun monitoring food orders in the area. See a tracker of Pentagon pizza orders here.

Nuclear-powered missiles replace chemical combustion with energy from nuclear fission

In these systems, energy is added to an airstream, which passes through a nozzle to generate thrust. Because the amount of energy released per unit mass of nuclear fuel is millions of times larger than that of chemical propellants, nuclear missiles can travel faster and farther with less fuel.

The most advanced 'bunker-buster' bomb can penetrate 200 feet below soil or concrete

The GBU-57 Massive Ordnance Penetrator is delivered exclusively by the B-2 Spirit stealth bomber, which carries only two at a time. Using GPS-guided fins and a steel alloy casing, it burrows 200 feet underground before detonating.

Presidents have temporarily transferred power under the 25th Amendment during medical procedures

Section 3 of the 25th Amendment lets presidents temporarily transfer authority—without permanently giving up the office. Reagan, George W. Bush, and Biden each invoked it during medical procedures, briefly making their vice presidents acting president.

North Korea's Kim Jong Un travels in a train with a helicopter and antiaircraft guns

The train, known as the Taeyangho (or "sun"), is a moving fortress, the country's equivalent of Air Force One. Its windows are bulletproof, exteriors built to withstand explosions, and heavy with armaments. Kim claims the train helps signal closeness to the people.

For decades, the US has considered building a permanent nuclear waste repository

All nuclear waste would have been stored at Nevada's Yucca Mountain, but the Obama administration indefinitely stalled the project after intense community backlash. Spent fuel is now stored at more than 80 locations in 36 states, raising safety concerns.

The quarterback cadence is a unique quirk to the game of football

Only the offense knows when the ball will be snapped, giving the team with the ball the advantage. Common combinations of colors and numbers (like "blue 42") were codes for plays early in the sport, but are now used arbitrarily.

'Keep working on a plan. Make no little plans. Make the biggest one you can think of, and spend the rest of your life carrying it out.'

- President Harry Truman (1884-1972)

Ten everyday NASA inventions (likely) in your home

The Challenger disaster exposed flawed priorities in NASA's leadership

Reported issues with the shuttle's O-rings were deemed "acceptable risks" to proceed with the launch and ensure President Reagan could mention the success of Challenger in his State of the Union address. Postponing the launch would have also limited the publicity of educator Christa McAuliffe's live lesson from space.
