USS Pueblo (AGER-2) is a Banner-class environmental research ship, attached to Navy intelligence as a spy ship, which was attacked and captured by North Korean forces on 23 January 1968, in what is known today as the "Pueblo incident" or alternatively, as the "Pueblo crisis".

The seizure of the U.S. Navy ship and her 83 crew members, one of whom was killed in the attack, came less than a week after President Lyndon B. Johnson's State of the Union address to the United States Congress, a week before the start of the Tet Offensive in South Vietnam during the Vietnam War and three days after 31 men of North Korea's KPA Unit 124 had crossed the Korean Demilitarized Zone (DMZ) and killed 26 South Koreans in an attempt to attack the South Korean Blue House (executive mansion) in the capital Seoul. The taking of Pueblo and the abuse and torture of her crew during the subsequent 11-month prisoner drama became a major Cold War incident, raising tensions between western and eastern powers.

North Korea stated that Pueblo deliberately entered their territorial waters 7.6 nautical miles (14 km) away from Ryo Island, and that the logbook shows that they intruded several times. However, the United States maintains that the vessel was in international waters at the time of the incident and that any purported evidence supplied by North Korea to support its statements was fabricated. Pueblo, still held by North Korea today, officially remains a commissioned vessel of the United States Navy. Since early 2013, the ship has been moored along the Pothong River in Pyongyang and used there as a museum ship at the Victorious War Museum. Pueblo is the only ship of the U.S. Navy still on the commissioned roster currently being held captive.

A bastion fort or trace italienne (a phrase improperly derived from French, literally meaning Italian outline), is a fortification in a style that evolved during the early modern period of gunpowder when the cannon came to dominate the battlefield. It was first seen in the mid-15th century in Italy. Some types, especially when combined with ravelins and other outworks, resembled the related star fort of the same era.

The design of the fort is normally a polygon with bastions at the corners of the walls. These outcroppings eliminated protected blind spots, called "dead zones", and allowed fire along the curtain from positions protected from direct fire. Many bastion forts also feature cavaliers, which are raised secondary structures based entirely inside the primary structure.

Since 2025, the second Donald Trump administration of the United States has sought to annex Greenland, an autonomous territory of Denmark (itself in the European Union), triggering an ongoing international diplomatic crisis. This escalated in early 2026 after Trump refused to rule out the use of military force to annex Greenland and threatened a 25% import tax on European Union (EU) goods unless Denmark ceded Greenland. Trump's statements sparked a confrontation with Denmark and the EU (supported by several other NATO members), reigniting earlier concerns of a US–EU trade war. On 21 January, Trump reversed his position at the 2026 Davos conference, pledging not to use force or tariffs to annex Greenland.

Trump had unsuccessfully tried to purchase Greenland during his first presidency. After his 2024 re-election, in January 2026, he said "it may be a choice" whether to preserve NATO or seize Greenland and that he "no longer [felt] an obligation to think purely of Peace" after not receiving the Nobel Peace Prize. A report by the Danish Defence Intelligence Service mentioned the United States (US) as a potential threat to national security for the first time in its history, and Danish officials raised concerns about reports that Director of National Intelligence Tulsi Gabbard had assigned agents to spy on Greenland.

The Greenlandic and Danish prime ministers rejected any US takeover, saying they would defend Greenland in the event of an attack. Both NATO and EU members would be obliged to assist Denmark in the event of an attack. Denmark and eight NATO allies deployed forces to defend the territory. In response, Trump threatened a trade war against the EU, leading European politicians to suspend a proposed EU–US trade agreement and consider placing sanctions on the US.

Trump's threats led to large-scale protests in both Greenland and Denmark. A YouGov poll found only 8% of Americans supported an invasion of Greenland, with 73% opposed. Trump's actions faced heavy opposition in Congress from both major parties, with Republican speaker of the House Mike Johnson describing Trump's threats as "completely inappropriate" and a bipartisan congressional delegation traveling to Copenhagen to support Denmark–US relations. The crisis was described as one of the most erratic episodes involving a US president, prompting scrutiny of Trump's age and fitness for office.

On 21 January, Trump reversed course, first ruling out military force and then abandoning tariff threats after talks with NATO secretary-general Mark Rutte reached what Trump called a "framework of a future deal". Greenland and Denmark ruled out any deal altering the sovereignty of Greenland and Denmark, with Trump's comments referring to pre-existing commitments from a 1951 US–Denmark treaty.

Project A119, also known as A Study of Lunar Research Flights, was a top-secret plan developed in 1958 by the United States Air Force. The aim of the project was to detonate a nuclear bomb on the Moon, which would help in answering some of the mysteries in planetary astronomy and astrogeology. If the explosive device detonated on the surface, not in a lunar crater, the flash of explosive light would have been faintly visible to people on Earth with their naked eye, a show of force resulting in a possible boosting of domestic morale in the capabilities of the United States, a boost that was needed after the Soviet Union took an early lead in the Space Race and was also working on a similar project.

The project was never carried out, being cancelled primarily out of a fear of a negative public reaction, with the potential militarization of space that it would also have signified, and because a Moon landing would undoubtedly be a more popular achievement in the eyes of the American and international public alike. A similar project by the Soviet Union also never came to fruition.

The existence of the US project was revealed in 2000 by a former executive at the National Aeronautics and Space Administration (NASA), Leonard Reiffel, who led the project in 1958. A young Carl Sagan was part of the team responsible for predicting the effects of a nuclear explosion in vacuum and low gravity and in evaluating the scientific value of the project. The project documents remained secret for nearly 45 years, and despite Reiffel's revelations, the United States government has never officially recognized its involvement in the study.

The Charlie Brown and Franz Stigler incident occurred on 20 December 1943, when, after a successful bomb run on Bremen, 2nd Lt Charles "Charlie" Brown's B-17 Flying Fortress (named "Ye Olde Pub") was severely damaged by German fighters. Luftwaffe pilot Franz Stigler had the opportunity to shoot down the crippled bomber but did not do so. After an extensive search by Brown, the two pilots met each other 50 years later and developed a friendship that lasted until Stigler's death in March 2008.

The OODA loop is the cycle observe–orient–decide–act, developed by military strategist and United States Air Force Colonel John Boyd. Boyd applied the concept to the combat operations process, often at the operational level during military campaigns. It is now also often applied to understand commercial operations and learning processes. The approach explains how agility can overcome raw power in dealing with human opponents. It is especially applicable to cyber security and cyberwarfare.

The OODA loop has become an important concept in litigation, business, law enforcement, management education, and military strategy. According to Boyd, decision-making occurs in a recurring cycle of observe–orient–decide–act. An entity (whether an individual or an organization) that can process this cycle quickly, observing and reacting to unfolding events more rapidly than an opponent, can thereby "get inside" the opponent's decision cycle and gain the advantage.

Project West Ford (also known as Westford Needles and Project Needles) was a test carried out by Massachusetts Institute of Technology's Lincoln Laboratory on behalf of the United States Military in 1961 and 1963 to create an artificial ionosphere above the Earth. This was done to solve a major weakness that had been identified in US military communications.

The ADE 651 is a fake bomb detector produced by the British company Advanced Tactical Security & Communications Ltd (ATSC). Its manufacturer claimed it could detect bombs, guns, ammunition, and more from kilometers away. However, it was a scam, and the device was little more than a dowsing rod. The device was sold for up to US$60,000 each, despite costing almost nothing to produce. It was widely used in the Middle East, and may have led to numerous deadly bombings in Iraq due to its inability to detect explosives. Its inventor, James McCormick, was sentenced to 10 years in prison in 2013 for fraud.

The Battle of the Beams was a period early in the Second World War when bombers of the German Air Force (Luftwaffe) used a number of increasingly accurate systems of radio navigation for night bombing in the United Kingdom. British scientific intelligence at the Air Ministry fought back with a variety of their own increasingly effective means, involving jamming and distortion of the radio waves. The period ended when the Wehrmacht moved their forces to the East in May 1941, in preparation for the attack on the Soviet Union.
