Honestly, France beat the British. Not America.
You know how the Korean War, although ostensibly a war between North and South Korea, was basically a war between the US and China? Yeah. The American Revolution was that, with Britain and France. Of course, our "AMERICA! FUCK YEAH!" school system and remnants of Manifest Destiny keep most people from thinking of it in those terms, but yeah, that's how it was. A small American rebellion persisted long enough to sap the British strength until some heavy aid from France was enough to shove them out of a war they no longer really cared for.
