On July 1st, 1968, the United States joined other major powers in signing the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Nuclear Non-Proliferation Treaty. For the military, this agreement did not remove existing nuclear forces, but it committed the country to limiting the spread of nuclear weapons technology and pursuing arms control talks over time.
With the Second World War over in Europe, Allied leaders grappled with how to respond to the crimes committed by the defeated regime.
After nearly three brutal months of fighting, American commanders declared the island of Okinawa secure on June 22nd, 1945. The campaign had begun with amphibious landings in April, followed by a grinding advance against deeply dug-in Japanese defenses that relied on cave systems, reverse-slope positions, and determined infantry counterattacks.
A story of a nearly lost beach, scattered initiative, and how small groups clawed back the chance to win a war.
A story of stealth jets, precision strikes, and a regime suddenly in the dark, and how it changed the wider war.
On November 9th, 1989, the emblem of Cold War division in Europe suddenly became porous.
As the twentieth century neared its end, the United States and its NATO allies faced a different kind of crisis in the Balkans. Tensions and violence in Kosovo, including the expulsion and abuse of ethnic Albanian civilians, raised alarms across Europe and North America. Diplomatic efforts failed to produce a settlement, and on March 24th, 1999, NATO launched Operation Allied Force, an air campaign aimed at pressuring the Yugoslav government to halt its operations and withdraw forces.
Just over a decade after Desert Storm, United States forces found themselves fighting a very different kind of war in Afghanistan. On March 2nd, 2002, Operation Anaconda began in the Shah-i-Kot Valley and surrounding high ground, as United States and allied troops attempted to encircle and destroy concentrations of al-Qaeda and Taliban fighters. The plan called for Afghan and coalition units to block escape routes while airlifted infantry swept through rugged terrain at high altitude.
By early 1962, American involvement in Vietnam was still officially described in terms of advisors, but the character of that involvement was already changing. On January 12th, 1962, Operation Chopper saw United States Army helicopters lift South Vietnamese troops into action against insurgent forces near Saigon. The mission may have seemed modest at the time, but it showcased the emerging doctrine of air mobility, using rotary-wing aircraft to move infantry quickly over difficult terrain.
During the Iran hostage crisis, the United States attempted a daring special operations mission to rescue embassy personnel held in Tehran. Code-named Operation Eagle Claw, the plan called for long-range transport aircraft and helicopters to rendezvous at a remote desert staging site, then move on toward the capital under cover of darkness. On April 24th, 1980, mechanical problems, dust, and the challenges of coordinating complex movements over great distances began to undermine the mission.
As North Vietnamese forces closed in on Saigon, American planners launched Operation Frequent Wind, the final phase of evacuations from South Vietnam. United States Marines secured key landing zones while waves of helicopters shuttled American personnel and at-risk South Vietnamese to ships waiting offshore. The images from that day—choppers crowding flight decks, overloaded aircraft, and helicopters pushed into the sea to make room for more arrivals—captured both urgency and heartbreak.
In mid-February 1944, two linked air operations signaled how the United States was using airpower to reshape two different theaters of war. On February 17th, fast carriers of the U.S. Pacific fleet launched Operation Hailstone against Truk Lagoon, a major Japanese base in the Central Pacific. Waves of aircraft struck ships at anchor, airfields, and support installations, sinking and damaging a large portion of the enemy fleet’s local strength and reducing Truk’s value as a forward bastion.
By 1969, the Vietnam War had become a grinding conflict, with North Vietnamese and Viet Cong forces using sanctuaries in nearby Cambodia and Laos to rest, resupply, and move along the Ho Chi Minh Trail. Seeking to disrupt those bases, President Richard Nixon authorized a series of secret bombing raids by B-52 bombers against selected locations inside Cambodia.
After months of retreat and uncertainty in the Korean War, the Eighth Army under Lieutenant General Matthew Ridgway prepared to strike back. On January 25th, 1951, United Nations forces launched Operation Thunderbolt, an offensive aimed at pushing north from positions south of Seoul and testing the strength of Chinese and North Korean units.
In the second year of the Korean War, United Nations forces under Lieutenant General Matthew Ridgway were pushing north in a series of offensives to reclaim ground lost during earlier Communist advances. As part of this effort, planners designed an airborne operation to cut off retreating North Korean and Chinese units and support the drive across the Han River.
While East Tennessee struggled under siege, another crucial city lay under Confederate observation at Chattanooga, a gateway through the mountains into the Deep South.
Before dawn on Leyte, the world was reduced to shadows, muzzle flashes, and the flat crack of Japanese rifles. Company A of the 382nd Infantry had clawed its way to the edge of the enemy‑held Buri airstrip, then stalled. Out in front, less than a hundred yards away, Japanese soldiers were dug into bomb craters and a drainage ditch, their machine guns perfectly sighted on every patch of open ground. Anyone who tried to move was met with bursts of fire that snapped past at chest height.
By February 1945, much of Pearl Harbor had returned to the business of war. Battleships and carriers came and went; convoys formed up and headed west toward Iwo Jima and Okinawa. But in a side channel called West Loch, the harbor still hid a graveyard. Months earlier, a chain of explosions had torn through a cluster of tank landing ships loading ammunition for the Pacific campaign.
Shortly before the United States entered the First World War, the Army found itself responding to a different kind of threat much closer to home. In the early hours of March 9th, 1916, fighters loyal to Mexican revolutionary leader Francisco “Pancho” Villa crossed the border and attacked the town of Columbus, New Mexico, as well as a nearby Army camp. The raid killed soldiers and civilians, burned buildings, and shocked a country that had long assumed the borderlands were secure.
On January 27th, 1973, delegations in Paris signed an agreement intended to end direct American involvement in the Vietnam War. The Paris Peace Accords called for a ceasefire, the withdrawal of United States combat forces, the return of prisoners of war, and a political process meant to reconcile rival Vietnamese governments. In practice, North Vietnamese units remained in the South, and both sides viewed the ceasefire through the lens of their own long-term goals.
On this night, a carefully prepared warning system in Massachusetts sprang into action as British regulars marched out of Boston toward Concord. Lanterns hung in a Boston church gave the first signal, and riders like Paul Revere and William Dawes carried the alarm through the countryside to local militia leaders. They were not lone heroes improvising on the spot but part of an organized network of patriot couriers, guides, and town committees.
While frontline units fought across oceans, the War Department was attempting to manage a truly global conflict from Washington. On January 15th, 1943, officials dedicated the Pentagon, a vast five–sided building designed to bring scattered offices under one roof. The new headquarters gave Army leadership a centralized nerve center for planning, logistics, and personnel management, replacing a confusing patchwork of leased buildings scattered around the capital.
In early 1916, a cross-border raid on Columbus, New Mexico by forces loyal to Mexican revolutionary Pancho Villa shocked the United States and demanded a response. On March 15th, the Army launched a punitive expedition under John J. Pershing, sending columns of cavalry, infantry, trucks, and even a small aviation detachment across the desert into northern Mexico. The mission aimed to capture Villa and deter further incursions while avoiding a full-scale war with Mexico’s government.
On July 4th, 1946, in Manila, the United States formally recognized the independence of the Republic of the Philippines, ending decades of colonial rule that had begun after the Spanish-American War. The ceremony marked a major shift in America’s role in the western Pacific, as a territory that had seen fierce fighting during the Second World War now stood as a sovereign partner.
