british, you are getting a bit silly here. let's look at ww2...

the brits were routed in pretty much every single meaningful engagement of the war. the battle of france was a joke. they were kicked out of greece. they were pushed from singapore and burma by the japs. they barely hung on in north africa against a much smaller force and only were victorious after the second front was opened up during operation torch. they forced a stalemate during the battle of britain only because hitler turned his attention east. they suffered insane causalties in the battle of caen including hundreds being mowed down marching out in the open like a bunch of idiots trying to take hill 112. operation market garden was a complete disaster led by one of the worst allied commanders of the was in montgomery. the best contribution of the war by the british were the code breakers and spy rings, not the boots on the ground, that's a fact.
