logistics win wars, america was instrumental in winning the war. deal with it. without american materiel coming across the atlantic, american ships carrying and escorting it, and american planes and bombs raping the fuck out of germany, the uk would have fallen by 1941 on account of having no oil to continue fueling their aircraft. the soviet union certainly did most of the heavy lifting on the ground war, and it's debatable whether or not they would have won without the allies tying germany up in the west and north africa and supplying materiel aid to them. but regardless, the uk and france can get fucked and suck a dick. america saved their asses and in hindsight i wish we hadn't.
