8 Wars involving South Korea

This is a list of wars involving South Korea and its predecessor states.

The Gulf War, codenamed Operation Desert Shield for operations leading to the buildup of troops and defense of Saudi Arabia and Operation Desert Storm in its combat phase, was a war waged by coalition forces from 35 nations led by the United States against Iraq in response to Iraq's invasion and annexation of Kuwait arising from oil pricing and production disputes.

The Iraq War was a protracted armed conflict that began in 2003 with the invasion of Iraq by a United States-led coalition that overthrew the government of Saddam Hussein. The conflict continued for much of the next decade as an insurgency emerged to oppose the occupying forces and the post-invasion Iraqi government. An estimated 151,000 to 1,033,000 Iraqis were killed in the first three to four years of conflict. US troops were officially withdrawn in 2011. However, following the spread of the Syrian Civil War and the territorial gains of the Islamic State of Iraq and the Levant (ISIL), the Obama administration decided to redeploy US forces to Iraq in 2014. Many former soldiers are employed by defense contractors and private military companies. The U.S. became re-involved in 2014 at the head of a new coalition; the insurgency and many dimensions of the civil armed conflict continue. The invasion occurred as part of the George W. Bush administration's War on Terror, following the September 11 attacks.

The Korean DMZ Conflict, also referred to as the Second Korean War by some, was a series of low-level armed clashes between North Korean forces and the forces of South Korea and the United States, largely occurring between 1966 and 1969 at the Korean DMZ.

The Korean War was a war between North Korea and South Korea. The war began on 25 June 1950 when North Korea invaded South Korea following clashes along the border and insurrections in the south. The war unofficially ended on 27 July 1953 in an armistice.

In the Vietnam War, after the assassinations of Ngo Dinh Diem and John F. Kennedy in late 1963 and the Gulf of Tonkin incident in 1964 and the continuing political instability in the South, the United States made a policy commitment to begin joint warfare in South Vietnam, a period of gradual escalation and Americanization, involving the commitment of large-scale combat forces from the United States and allied countries. It was no longer assumed the Republic of Vietnam could create a desirable situation without major external assistance. This phase of the war lasted until the election of Richard Nixon, and the change of U.S. policy to Vietnamization, or giving the main combat role back to the South Vietnamese military.

The War on terror, also known as the Global War on Terrorism and U.S. War on Terror, is an international military campaign launched by the United States government after the September 11 attacks. The targets of the campaign are primarily Sunni Islamic fundamentalist armed groups located throughout the Muslim world, with the most prominent groups being Al-Qaeda, the Islamic State, the Taliban, Tehrik-i-Taliban Pakistan, and the various franchise groups of the former two organizations. The naming of the campaign uses a metaphor of war to refer to a variety of actions that do not constitute a specific war as traditionally defined. U.S. 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. In the latter speech, George Bush stated, "Our enemy is a radical network of terrorists and every government that supports them." The term was originally used with a particular focus on countries associated with al-Qaeda. The term was immediately criticised by such people as Richard B. Myers, chairman of the Joint Chiefs of Staff, and more nuanced terms subsequently came to be used by the Bush administration to publicly define the international campaign led by the U.S. While it was never used as a formal designation of U.S. operations in internal government documentation, a Global War on Terrorism Service Medal was issued.

The Vietnam War, also known as the Second Indochina War, and in Vietnam as the Resistance War Against America or simply the American War, was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. North Vietnam was supported by the Soviet Union, China, and other communist allies; South Vietnam was supported by the United States, South Korea, the Philippines, Australia, Thailand, and other anti-communist allies. The war, considered a Cold War-era proxy war by some, lasted 19 years, with direct U.S. involvement ending in 1973, and included the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist in 1975.
