How about we make the point between the USA and France on who won and lost more wars ?
USA
Major wars won mostly alone
- Mexican–American War of 1846-48
- Spanish-American War of 1898
- WWII in the Pacific
- Gulf War of 1991
Major wars won in coalition
- US war of independence (won with France)
- WWI (the US didn't actually do much compared to France and Britain)
- WWII in Europe (the USSR did probably more than the US in defeating Hitler)
Major wars lost
- Civil War (cannot be considered as "won" with so many casualties)
- Vietnam War (the longest war waged by the US)
- Iraq War (the latest war waged by the US)
France
Major wars won mostly alone
- Hundred Years' War (1337-1453)
- War of Spanish Succession by Louis XIV (1701–1714 - alone against Europe)
- French Revolutionary Wars (1792-1802 - annexed the Benelux and Northern Italy, defeated the Austrian Empire)
- Napoleonic Wars (1804-1814 - alone against Europe again)
Major wars won in coalition
- US war of independence
- WWI
Major wars lost
- 1870 Franco-German War
- WWII (although ultimately won thanks to allied supoport)
Conclusion
In coalition, the US and France won mostly the same wars, some mostly won by the US with some French support (US independence), and others won mostly by France with some US support (WWI).
The US only managed to win a war alone against developing countries much smaller than itself (Mexico, Panama, Iraq, Japan in the 1940's). France regularily won against the strongest European powers of the time for many centuries. France also won against small developing countries, during the colonial period, and had much more colonies than the US ever had, even in the 20th century.
The US was defeated by developing nations (Vietnam, Iraq) and by itself. France only lost twice, both to Germany, a more populous country of the same level of development.
