has america ever won a war that they have fought by themselves (civil war does not count )?

Barbary Wars

War of 1812

Mexican War

Blackhawk War

Plains Wars

Spanish American War

Punitive Expedition to Mexico

Phillipine Insurrection

Banana Wars

Grenada

Panama

All wars or conflicts fought and won without allies

Spanish American War. War with Mexico. War of 1812.

Yes quite a few. But when wars occur, it's not unusual for multiple countries to be involved. Thus you have allies (and additional enemies).

Spanish-American war and Mexican American war. I apologize if I'm incorrect though, im lacking info on those two conpared to others

america has never faught a war, just by itself

thats why a country has allies

Yeah sure. The war against the Mexicans when we stole Texas. Or the war against the Natives when we stole the entire country from them.

Yes, the USA won several illegal and imperialistic wars all by themselves. The US-Mexican war in the 1840s, for example.

WWII

No.
