You keep on referring to it as a british defeat, but it was a joint effort between britian and France :). Iirc, the US didn't need to crash the british economy, they simply threatened to devalue the pound, denounced the invasion publicly, then the europeans called a ceasefire (unilaterally? I'm not sure). At no point in either the french nor the british military operations do you see either tactical defeats or supply issues.
