Operation Enduring Freedom (OEF) was the official name used by the U.S. government for both the first stage (2001–2014) of the War in Afghanistan (2001–2021) and the larger-scale Global War on Terrorism. On 7 October 2001, in response to the September 11 attacks, President George W. Bush announced that airstrikes against Al-Qaeda and the Taliban had begun in Afghanistan. Beyond the military actions in Afghanistan, Operation Enduring Freedom was also affiliated with counterterrorism operations in other countries, such as OEF-Philippines and OEF-Trans Sahara.
The International Security Assistance Force (ISAF) was a multinational military mission in Afghanistan from 2001 to 2014. It was established by United Nations Security Council Resolution 1386 according to the Bonn Agreement, which outlined the establishment of a permanent Afghan government following the U.S. invasion in October 2001. ISAF's primary goal was to train the Afghan National Security Forces (ANSF) and assist Afghanistan in rebuilding key government institutions; it gradually took part in the broader war in Afghanistan against the Taliban insurgency.
A no-fly zone, also known as a no-flight zone (NFZ), or air exclusion zone (AEZ), is a territory or area established by a military power over which certain aircraft are not permitted to fly. Such zones are usually set up in an enemy power's territory during a conflict for humanitarian or military reasons without consent of the enemy state, similar in concept to an aerial demilitarized zone, and usually intend to prohibit the enemy's military aircraft from operating in the region. Military action is employed by the enforcing state and, depending on the terms of the NFZ, may include preemptive attacks to prevent potential violations, reactive force targeted at violating aircraft, or surveillance with no use of force. Air exclusion zones and anti-aircraft defences are sometimes set up in a civilian context, for example to protect sensitive locations, or events such as the 2012 London Olympic Games, against terrorist air attack. A no-fly zone is generally not considered a form of aerial blockade due to its more limited scope compared to an aerial blockade.
This timeline of United States military operations, based in part on reports by the Congressional Research Service, shows the years and places in which United States Armed Forces units participated in armed conflicts or occupation of foreign territories. Items in bold are wars most often considered to be major conflicts by historians and the general public.
Operation Deny Flight was a North Atlantic Treaty Organization (NATO) operation that began on 12 April 1993 as the enforcement of a United Nations (UN) no-fly zone over Bosnia and Herzegovina. The United Nations and NATO later expanded the mission of the operation to include providing close air support for UN troops in Bosnia and carrying out coercive air strikes against targets in Bosnia. Twelve NATO members contributed forces to the operation and, by its end on 20 December 1995, NATO pilots had flown 100,420 sorties.
Shortly after the September 11 attacks, the United States declared the war on terror and subsequently led a multinational military operation against Taliban-ruled Afghanistan. The stated goal was to dismantle al-Qaeda, which had executed the attacks under the leadership of Osama bin Laden, and to deny Islamist militants a safe base of operations in Afghanistan by toppling the Taliban government. The United Kingdom was a key ally of the United States, offering support for military action from the start of the invasion preparations. The American military presence in Afghanistan greatly bolstered the Northern Alliance, which had been locked in a losing fight with the Taliban during the Afghan Civil War. Prior to the beginning of the United States' war effort, the Taliban had seized around 85% of Afghanistan's territory as well as the capital city of Kabul, effectively confining the Northern Alliance to Badakhshan Province and smaller surrounding areas. The American-led invasion on 7 October 2001, marked the first phase of what would become the 20-year-long War in Afghanistan.
Operation Herrick was the codename under which all British operations in the War in Afghanistan were conducted from 2002 to the end of combat operations in 2014. It consisted of the British contribution to the NATO-led International Security Assistance Force (ISAF), and support to the American-led Operation Enduring Freedom (OEF), within the country.
The foreign policy of the Bill Clinton administration was of secondary concern to a president fixed on domestic policy. Clinton relied chiefly on his two experienced Secretaries of State Warren Christopher (1993–1997) and Madeleine Albright (1997–2001), as well as Vice President Al Gore. The Cold War had ended and the Dissolution of the Soviet Union had taken place under his predecessor President George H. W. Bush, whom Clinton criticized for being too preoccupied with foreign affairs. The United States was the only remaining superpower, with a military strength far overshadowing the rest of the world. There were tensions with countries such as Iran and North Korea, but no visible threats. Clinton's main priority was always domestic affairs, especially economics. Foreign-policy was chiefly of interest to him in terms of promoting American trade. His administration signed more than 300 bilateral trade agreements. His emergencies had to do with humanitarian crises which raised the issue of American or NATO or United Nations interventions to protect civilians, or armed humanitarian intervention, as the result of civil war, state collapse, or oppressive governments.
Following the September 11 attacks in 2001, several countries began military operations against Al-Qaeda and the Taliban during Operation Enduring Freedom (OEF) in Afghanistan. After the initial bombing operations, Operation Crescent Wind, OEF was the initial combat operations, and during 2002 and 2003.

Events from the year 2007 in Afghanistan.
The United States government has been involved in numerous interventions in foreign countries throughout its history. The U.S. has engaged in nearly 400 military interventions between 1776 and 2023, with half of these operations occurring since 1950 and over 25% occurring in the post-Cold War period. Common objectives of U.S. foreign interventions have revolved around economic opportunity, social protection, protection of U.S. citizens and diplomats, territorial expansion, fomenting regime change, nation-building, and enforcing international law.
The war on terror, officially the Global War on Terrorism (GWOT), is a global counterterrorist military campaign initiated by the United States following the September 11 attacks of 2001, and is the most recent global conflict spanning multiple wars. Some researchers and political scientists have argued that it replaced the Cold War.
The War in Afghanistan was an armed conflict that took place from 2001 to 2021. Launched as a direct response to the September 11 attacks, the war began when an international military coalition led by the United States invaded Afghanistan, declaring Operation Enduring Freedom as part of the earlier-declared war on terror, toppling the Taliban-ruled Islamic Emirate, and establishing the Islamic Republic three years later. The Taliban and its allies were expelled from major population centers by US-led forces supporting the anti-Taliban Northern Alliance; Osama bin Laden, meanwhile, relocated to neighboring Pakistan. The conflict officially ended with the 2021 Taliban offensive, which overthrew the Islamic Republic, and re-established the Islamic Emirate. It was the longest war in the military history of the United States, surpassing the length of the Vietnam War (1955–1975) by approximately six months.
Events from the year 2010 in Afghanistan.
This article summarizes the history of the War in Afghanistan (2001–2021).
On 15 August 2021, the city of Kabul, the capital of the Islamic Republic of Afghanistan, was captured by Taliban forces during the 2021 Taliban offensive, concluding the War in Afghanistan that began in 2001. The fall of Kabul provoked a range of reactions across the globe, including debates on whether to recognize the Taliban as the government of Afghanistan, on the humanitarian situation in the country, on the outcome of the War, and the role of military interventionism in world affairs.
Large-scale evacuations of foreign citizens and some vulnerable Afghan citizens took place amid the withdrawal of US and NATO forces at the end of the 2001–2021 war in Afghanistan. The Taliban took control of Kabul and declared victory on 15 August 2021, and the NATO-backed Islamic Republic of Afghanistan collapsed. With the Taliban controlling the whole city except Hamid Karzai International Airport, hostilities ceased and the Taliban assisted in the evacuation effort by providing security and screening evacuees.
