Osama bin Laden declared jihad—a call for armed struggle framed as a religious duty—against the US in 1996.

Before 9/11, al-Qaeda carried out several deadly attacks on US targets—including the 1998 embassy bombings in Kenya and Tanzania and the 2000 bombing of the USS Cole—killing hundreds of people.

The group emerged in 1988 from the militant networks formed during the Soviet-Afghan War. Under Osama bin Laden's leadership, it combined jihadist ideology with global ambitions—eventually orchestrating attacks across Africa, the Middle East, Europe, and the United States.

In the wake of 9/11, the US declared a Global War on Terror—initiating military operations in Afghanistan and Iraq, expanding surveillance, and forming international coalitions to combat terrorism and disrupt extremist networks worldwide.

US and Pakistani support for Afghan mujahideen in the 1980s inadvertently built the infrastructure—training camps, ideology, and global fighters—that later evolved into al-Qaeda's foundation.

A fundamentalist Islamist movement, the Taliban ruled most of Afghanistan before 9/11, providing al-Qaida with training grounds and sanctuary. After 20 years of war, it regained power following the U.S. withdrawal in 2021.

The collective defense clause of the NATO constitution has only been invoked one time: after the 9/11 terrorist attacks against the United States. This video explores the immediate actions NATO took to respond to the attacks to support the United States. These firsthand clips from 2001 give a sense of the magnitude of the moment and the difficult decisions facing NATO leaders at the time.

As part of the intelligence operation to find bin Laden in Pakistan, the US Central Intelligence Agency recruited a Pakistani doctor who ran a fake hepatitis B vaccine campaign and obtained DNA samples from bin Laden. News of this fake campaign fueled further distrust of healthcare workers, attacks on them, and stymied efforts to vaccinate against polio in the region.

Following the June 1967 Arab–Israeli war, Saudi Arabia, Kuwait, Iraq, Libya, and Algeria embargoed oil shipments to the US, UK, and West Germany. While the move did not have a large impact, it reshaped global oil flows, and foreshadowed OAPEC's later actions.

As part of its post-9/11 strategy, the US employed enhanced interrogation, extraordinary rendition, and secret CIA black sites—practices widely criticized as torture and violations of international law and human rights.

Despite having no treaty obligation to join Japan’s fight, Hitler declared war on the US on Dec. 11, 1941. The move pulled America into the European theater and is widely seen as one of Hitler’s most strategic blunders.

The article was invoked the day after the attacks and launched a series of NATO campaigns to fight global terrorism. This page includes excerpts from a speech by then-NATO Secretary General Jens Stoltenberg about the attacks and the organization’s response.

American Airlines Flight 77 crashed into the Pentagon's west side, destroying a section of the building and killing all 59 on board, along with 125 military and civilian personnel, making it the deadliest attack on the US military headquarters.

In a Gallup poll taken days after the attack, an extraordinary 97% of Americans approved Congress declaring war on Japan—reflecting overwhelming national unity in the wake of the strike.

In the weeks following 9/11, 79% of US adults reported displaying the American flag, and a year later, 62% said they "often felt patriotic" due to the attacks.

United Airlines Flight 93 was hijacked en route to Washington, DC. Passengers learned of the other attacks and stormed the cockpit. The plane crashed in Pennsylvania, likely preventing a strike on the US Capitol.

This video explores how economic pressures—like rising debt and oil disputes—combined with political ambitions pushed Iraq, under Saddam Hussein, to invade Kuwait on August 2, 1990, triggering the Gulf War.

The five declared wars were the War of 1812, the Mexican-American War, the Spanish-American War, World War I, and World War II. Every major American military conflict since Korea, Vietnam, Iraq, and Afghanistan has been fought without a formal declaration.

While Palantir has never publicly confirmed the use of its software in the 2011 assassination, its technology is widely speculated to have been a critical aspect of the operation. However, Palantir executives have never denied the claim, either, and have frequently commented on the software's important role in defending Western civilizations from terrorism.

Instead of formally declaring war, Congress passed the Gulf of Tonkin Resolution in 1964, granting President Johnson broad authority to use military force. The resolution became the legal basis for escalating US involvement without an official declaration of war.

By establishing the world's first modern Islamic theocracy, the revolution inspired Islamist movements across the region and alarmed Sunni Arab governments. The resulting rivalry between Shia Iran and Sunni Saudi Arabia has since fueled proxy conflicts in Lebanon, Iraq, Syria, and Yemen that persist today.

In August 1964, Washington claimed that North Vietnam launched two attacks on US destroyers in the Gulf of Tonkin. The second, used to justify escalating the US war effort, was later revealed to most likely have been a radar mistake.

Oliver Stone's film "JFK" (1991) imagined the 1963 assassination of President John F. Kennedy as the result of a conspiracy by US government agents. Before the film, this belief was not common, but it became widely adopted afterward. The film's impact contributed to the release of major CIA files in subsequent decades.

Beyond authorizing military force abroad, a formal declaration activates a wide range of domestic powers, including authority over enemy property, trade restrictions, and emergency economic authority. It also waives the 60-day time limits under the War Powers Resolution.

Despite breaking Japan’s diplomatic codes, US agencies failed to integrate warnings, successfully track Japan’s carriers, or even believe a Hawaii strike was possible (they also had not cracked Japan’s naval codes). Missed signals, ignored reports and poor coordination led to one of the worst intelligence failures in US history.

Signed into law weeks after the attacks, the PATRIOT Act granted federal agencies sweeping powers to monitor communications, access records, and conduct surveillance—sparking ongoing debates over privacy, civil liberties, and national security.

Decades before Pearl Harbor, the US held major Pacific territories—Hawaii, the Philippines, Guam, American Samoa, and numerous island bases—giving it strategic reach across the western Pacific. This presence increasingly overlapped with Japan’s imperial ambitions in the region, contributing to rising tensions.

The US led a boycott of the 1980 Moscow Olympics over the Soviet invasion of Afghanistan. In retaliation, the USSR and its allies skipped the 1984 Los Angeles Games.

Toward the end of Ramadan, Laylat al-Qadr is observed, recalling Muhammad's "night of power" when the Quran was first revealed, according to Islamic tradition. The Quran describes it as better than a thousand months of worship. Its exact date differs between Sunni and Shia adherents, falling on the 27th night of the month for Sunnis and the 23rd for Shias.

In 2002, George W. Bush became the first president to livestream the State of the Union, using the address to label Iraq, Iran, and North Korea an "axis of evil," shaping US strategy during the War on Terror.

This video navigates the conflict’s core—from Iraq's August 2, 1990 invasion of Kuwait through Operation Desert Shield’s buildup, to the decisive air and ground assault of January–February 1991. It spotlights coalition tactics and rapid liberation of Kuwait, highlighting how precision bombing and advanced tech reshaped modern warfare.

This video traces how US-led sanctions and Japan’s near-total dependence on imported oil pushed Japanese leaders toward a high-risk plan: seize Southeast Asian oil fields and neutralize the American Pacific Fleet, hoping Washington would negotiate rather than fight.

On Nov. 26, 1941, Secretary of State Cordell Hull issued a note calling on Japan to withdraw from China and Indochina—terms Tokyo saw as impossible. The note confirmed to Japanese leaders that diplomacy had collapsed, accelerating plans for the Pearl Harbor strike (which had been formally approved Nov. 5).
