Wars involving the United States
Wars involving the United States encompass armed conflicts in which the United States or its predecessors—the Thirteen Colonies and the United States of America (Continental Congress)—participated from colonial skirmishes to global campaigns. These conflicts include colonial-era engagements such as the French and Indian War, the American Revolutionary War, 19th-century expansionist wars like the Mexican–American War, major 20th-century conflicts such as the World War I and World War II, Cold War proxy wars including the Korean War and the Vietnam War, and post-9/11 operations like the War in Afghanistan (2001–2021) and the Iraq War.
Overview and historical context
From contests between British America and New France to interventions in the Philippine–American War and occupations in Germany and Japan, United States military engagements have shaped international orders such as the Treaty of Paris (1783), the Versailles Treaty, and the United Nations Charter. Influences include doctrines like the Monroe Doctrine, the Truman Doctrine, and the Bush Doctrine, with policy drivers tied to figures such as George Washington, Thomas Jefferson, Abraham Lincoln, Theodore Roosevelt, Franklin D. Roosevelt, Harry S. Truman, Dwight D. Eisenhower, John F. Kennedy, Lyndon B. Johnson, Richard Nixon, Ronald Reagan, George W. Bush, and Barack Obama. Major battles and campaigns—Saratoga, Gettysburg, Midway, Normandy landings, Inchon landing, Tet Offensive, Fallujah—illustrate tactical evolution across eras, while treaties such as the Treaty of Ghent, the Treaty of Paris (1898), the Korean Armistice Agreement, and the Camp David Accords mark political outcomes.
Colonial and Revolutionary-era conflicts
Early conflicts included colonial expeditions like King Philip's War, frontier actions involving Powhatan Confederacy, and imperial wars such as the Seven Years' War. The French and Indian War set the stage for fiscal and political strains culminating in the American Revolutionary War, featuring leaders George Washington, John Adams, Benjamin Franklin, and battles at Lexington and Concord, Bunker Hill, Saratoga, and the Siege of Yorktown. Diplomatic instruments such as the Treaty of Paris (1783) and alliances with France and figures like Comte de Rochambeau and Marquis de Lafayette were decisive.
19th-century wars and expansionism
The 19th century saw the War of 1812 against Great Britain, engagements with Tecumseh and battles like New Orleans, the Mexican–American War leading to the Treaty of Guadalupe Hidalgo, and the American Civil War between the Union and the Confederate States of America with commanders Ulysses S. Grant, Robert E. Lee, and battles at Gettysburg and Antietam. Overseas expansion included the Spanish–American War, the Philippine–American War, the Banana Wars in Central America and the Caribbean, and conflicts with indigenous nations during the American Indian Wars such as the Battle of Little Bighorn and the Wounded Knee Massacre.
20th-century global wars and interventions
The United States mobilized for World War I under Woodrow Wilson, participating in the Second Battle of the Marne and attending the Paris Peace Conference. In World War II, the U.S. fought campaigns across the European Theater and Pacific Theater, engaging in Operation Overlord, the Battle of the Bulge, Battle of Midway, Iwo Jima, and dropping atomic bombs on Hiroshima and Nagasaki; leaders included Franklin D. Roosevelt and Harry S. Truman. Interventions and occupations followed in Germany, Japan, Korea (post-1945), and China during the Chinese Civil War context. Other 20th-century actions included the Lebanon crisis (1958), the Bay of Pigs Invasion, the Dominican Civil War (1965), and multinational operations in Bosnia and Herzegovina and Kosovo.
Cold War and proxy conflicts
During the Cold War, the United States contested the Soviet Union and People's Republic of China via proxy wars and interventions: the Korean War, the Vietnam War including the Tet Offensive and Khe Sanh, the Bay of Pigs Invasion, and covert actions by the Central Intelligence Agency in Iran (1953) and Guatemala (1954). The U.S. supported anti-communist forces in the Angolan Civil War, the Nicaraguan Contra War, and Afghanistan (1979–1989) against the Soviet–Afghan War through programs like Operation Cyclone. Crises included the Berlin Blockade, the Cuban Missile Crisis, and arms control efforts such as the Strategic Arms Limitation Talks.
Post-9/11 wars and counterterrorism operations
Following the September 11 attacks, the United States launched Operation Enduring Freedom and the War in Afghanistan (2001–2021), pursued the Iraq War after Operation Iraqi Freedom, and conducted operations against Al-Qaeda, ISIS, and other groups through United States Special Operations Command and coalition partners like NATO and the Coalition of the Willing. Notable events include the Battle of Tora Bora, the capture of Baghdad, the Abu Ghraib scandal, targeted strikes such as the raid that killed Osama bin Laden, and campaigns like Operation Inherent Resolve. Regional tensions involved engagements with Iran, Syria, Yemen (including Operation Decisive Storm and Operation Restoring Hope contexts), and maritime security in the Strait of Hormuz.
Impact, casualties, and legacy
U.S. wars have produced profound human, political, and legal consequences: casualty figures across conflicts like the American Civil War, World War II, the Vietnam War, and the Iraq War affected veterans, populations, and veterans’ healthcare under institutions such as the Department of Veterans Affairs. Legal and normative outcomes include the Geneva Conventions, war crimes tribunals at Nuremberg and Tokyo, debates over Habeas Corpus and Patriot Act provisions, and doctrines shaping international law and institutions like the United Nations. Memorialization occurs at sites such as the National Mall, Arlington National Cemetery, the Vietnam Veterans Memorial, and the National World War II Memorial, while historians—Ike Eisenhower-era scholars and modern analysts—continue reassessing interventions from the perspectives of figures like Howard Zinn and institutions like the RAND Corporation.
