War on terror

Overview

The war on terror, officially the Global War on Terrorism (GWOT), is a global military campaign initiated by the United States in response to the September 11 attacks in 2001. A global conflict spanning multiple wars, some researchers and political scientists have argued that it replaced the Cold War.

The main targets of the campaign were militant Islamist movements such as al-Qaeda, the Taliban, and their allies. Other major targets included the Ba'athist regime in Iraq, which was deposed in an invasion in 2003, and various militant factions that fought during the ensuing insurgency. Following its territorial expansion in 2014, the Islamic State also emerged as a key adversary of the United States. In 2026, the United States and Israel launched a war on Iran, identifying it as the largest state sponsor of terrorism. Al-Qaeda's de facto leader, Saif al-Adel, is believed to be living in Iran.

The term "war on terror" uses war as a metaphor to describe a variety of actions which fall outside the traditional definition of war. US president George W. Bush first used the term "war on terrorism" on 16 September 2001, and then "war on terror" a few days later in a formal speech to Congress. Bush indicated the enemy of the war on terror as "a radical network of terrorists and every government that supports them". The initial conflict was aimed at al-Qaeda, with the main theater in Afghanistan and Pakistan, a region that would later be referred to as "AfPak". The term "war on terror" was immediately criticized by individuals including Richard Myers, then chairman of the Joint Chiefs of Staff, and eventually more nuanced terms came to be used by the Bush administration to define the campaign. While "war on terror" was never used as a formal designation of US operations, a Global War on Terrorism Service Medal was and is issued by the US Armed Forces.

According to the Costs of War Project, the post-9/11 wars of the campaign have displaced 38 million people, the second largest number of forced displacements of any conflict since 1900, and caused more than 4.5 million deaths (direct and indirect) in Afghanistan, Iraq, Libya, Pakistan, Somalia, Syria and Yemen. They also estimate that it has cost the US Treasury over $8 trillion.

While support for the "war on terror" was high among the American public during its initial years, it had become deeply unpopular by the late 2000s. Controversy over the war has focused on its morality, casualties, and continuity, with critics questioning government measures that infringed civil liberties and human rights. Critics have notably described the Patriot Act as "Orwellian" due to its substantial expansion of the federal government's surveillance powers. Controversial practices of coalition forces have been condemned, including drone warfare, surveillance, torture, extraordinary rendition, and various war crimes. The participating governments have been criticized for implementing authoritarian measures, repressing minorities, fomenting Islamophobia globally, and causing negative impacts to health and environment. Security analysts assert that there is no military solution to the conflict, pointing out that terrorism is not an identifiable enemy, and have emphasized the importance of negotiations and political solutions to resolve the underlying roots of the crises.

Starting in 2025, Operation Southern Spear emerged as an extension of the war on terror adapted to combat narcoterrorism in Latin America, with the US government utilizing the same legal frameworks established in 2001 to justify the use of lethal force. Some analysts have identified this new approach as a hybridization of the war on terror and the war on drugs.

The scope of the Great War furnishes an urgent as well as convenient starting point for the discussion. The extent of that war is unparalleled, because the conditions involved in it are so new. The dynastic conflicts of the seventeenth century are called by the same name: we have only one word, “war.” The sameness of the word too easily conceals from us the difference in significance. We think of all wars as much…

Hereby it is manifest, that during the time men live without a common Power to keep them all in awe, they are in that condition which is called Warre; and such a warre, as is of every man, against every man.
