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.
With 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”

As for the United States itself, the most obvious example is the American Civil War (1861-65).
The US federal government (Union) defeated the secessionist Confederate States of America which included 11 current US states, of which Virginia, North Carolina, South Carolina and Georgia were all part of the original 13 US states.
However, there were also the American Indian Wars (1600s–1890s). 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 a 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)

Andrew says
I’d not include uprisings or rebel incitements or even the Russian Civil War. I’d say the only true defeats were Afghanistan, Vietnam, Cuba, Niger, Somalia, UK/Canada.
Wayne Wager says
The Pueblo incident was a lost war? We’ve all heard the expression they “lost the battle but won the war”. In the English language “war” is a full scale affair. In the case of the Pueblo, I would say even battle is too dramatic a word. It was a skirmish during the Cold War. We won the Cold War. We might say today that we won Cold War I. and that Cold War II — The Drone Wars, is in its early stages. I hope that’s not too prophetic.
Marshal Shichtman says
Your definition of “militarily defeated” is highly suspect.
This is a problem because is calls your judgement in everything else into question.
Examples:
The US lost Viet Nam; no doubt. But you listed the US losing the War of 1812. (which I would concur with, but for…) If you use the same logic that the US lost in Viet Nam, opposition left and indigenous remained, then the US “won” the War of 1812. You don’t have to be “right” in your conclusions, you just have to be consistent.
However, you use that same logic in Afghanistan, consistently. But to say the US was “militarily defeated” in Afghanistan is a stretch in anyone’s book. Failure to achieve a permeant goal, maybe. (area control for two decades would be long term objective achievement)
Failure to stop the creation of the Soviet Union. I think your standards are unrealistic.
In sum and substance, the loss of personnel and equipment, or the failure of an operation, or the failure of a permeant objective, would mean everyone has lost against everyone.
I know that I am not going to change your mind. I know the US isn’t perfect. And in the US, you are entitled to your opinion. But when you make sweeping conclusions without any objective criteria, context, or perspective, it calls your judgement and credibility into question.
I will continue to read your emails, but it is no longer information, it is entertainment.
james mccarty yeager says
i was taught US colonial history by an australian at the university of toronto. painfully clear the US lost the war of 1812 — even after a sneak attack to open the war without any diplomatic notice. a la pearl harbour, really. but you left out the time the israeli air force and navy shot up a US intelligence vessel, USS liberty, in the mediterranean in 1967. that little conflict was certainly a US defeat as well.
Charles Berger says
Battle of the Bulge was the US Army’s biggest triumph of WW2…. Definitely not a German win!
Robert Johnson says
1) 1812 ended in stalemate after concluding unfinished War of Independence business
2) It was against Britain. Canada wasn’t a country.
James Gooch says
The list seems reasonable overall. The two points I would question:
1) In the War of 1812, the present-day Commonwealth didn’t exist yet. I would prefer to attribute the victory to the “British Empire”, or some similar term which seems more historically accurate.
2) Operation Eagle Claw did fail, but I wouldn’t count it as having been ‘militarily defeated’ when they never fought; even the Iranian government didn’t take credit for it! If we gave credit to anyone I’d say that the US defeated itself by doing everything poorly.
Brilliant Maps says
Yeah, the War of 1812 is somewhat contentious one. Canadians would swear it was us that burned down the Whitehouse, but I think looking objectively it was more the British. That said as a Canadian I’m keeping it.
Operation Eagle Claw is yet another example of “It’s Complicated.”
