The map above shows which countries the US has lost wars or other military conflicts to. However, defining what is a loss is very tricky.For example, during World War 2 the Japanese completely defeated the United States at Pearl Harbour, but would go on to lose the war (so not included).Similarly, the Germans also inflicted limited defeats on the US (Battle of Kasserine Pass, Battle of the Bulge, etc), but also went on to lose the war (so again not included).Therefore, I’ve used Lists of wars involving the United States and included any country they consider as having been at war/conflict with the United States and their view on if the US lost.There is one notable exception, Wikipedia lists the result of the War of 1812 as having been inconclusive, but as Canadian Brit I can’t see how the US didn’t lose the war.The British/Canadians burned down the White House and stopped the US from annexing Canada (probably a lesson in there somewhere).Below is a full list of wars and conflicts the US lost and who they lost to. And below that I talk a bit more about the US itself being complicated.Note some of these conflicts do really stretch the definition of “war”War/Conflict NameFaught AgainstYear(s)ResultMoroccan seizure of the BetseyMorocco1784U.S. forced to pay $30,000 ransomAmerican–Algerian WarRegency of Algiers1785–1795The U.S. government agrees to pay an annual tribute of $21,600Chesapeake–Leopard affairUnited Kingdom1807The USS Chesapeake was bordered and 4 of her crew impressed into British service.Patriot War (Florida)Spain1812–1814US abandon filibuster allies for fear of expanded conflict with SpainWar of 1812United Kingdom including Canada1812-1815- Commonwealth troops burn the White House-US fails in its attempts to invade and occupy Canada.- 2,200 Americans killed in action, 5,200 died of disease and up to 15,000 deaths from all causes Formosa ExpeditionPaiwan (Taiwan)1867United States Navy and Marine company retreat without accomplishing anythingRussian Civil WarSoviet Russia1918–1920- 424 Americans killed- Failure to prevent the creation of the Soviet UnionTurkish War of IndependenceTurkey1919–1922- King-Crane Commission Plan not implemented- Establishment of the Republic of TurkeyOperation ValuableAlbania1949–1956- Failure to overthrow the communist regime of Enver Hoxha in Albania- 300 MI6 and CIA agents killed during its durationAir battle over MerklínCzechoslovak Republic1953- American F-84 fighter-bomber shot downVietnam WarNorth Vietnam, Viet Cong, Pathet Lao, Khmer Rouge, GRUNK, China, Soviet Union, North Korea1955 -1975- Withdrawal of American forces from Indochina- North Vietnamese victory over South Vietnam - Reunification of North Vietnam and South Vietnam into the communist state Socialist Republic of Vietnam- Communist governments take power also in Laos and CambodiaPermesta RebellionIndonesia1958–1961Permesta surrendered to Indonesia governmentTibetan uprisingPeople's Republic of China1959Flight of the 14th Dalai Lama to IndiaLaotian Civil WarPathet Lao, North Vietnam1959–1975- The fall of the Kingdom of Laos- Establishment of the communist state Lao People's Democratic RepublicBay of Pigs InvasionCuba1961- Failure to topple Castro's government- Increased cooperation between Cuba and the Soviet Union, leading to the Cuban missile crisis.

The US Federal government would ultimately “tame the west,” but they lost several wars and battles to native groups that would eventually become US citizens.Here is partial list:St. Clair’s defeat (1791)First & Second Seminole War (1817-18; 1835–1842)Red Cloud’s War (1866–1868)Battle of the Little Bighorn (1876)What do you think of the list above?
