My father-in-law was in the first wave on Gold, paramedic you would call him nowadays. Spent the next two years or so attached to various active units ending up with an armoured brigade that liberated Auschwitz. There was a reason America chose to prioritise the European campaign. Hitler was almost as advanced as America in developing a nuclear capability. Liberating Europe wasn't "simply" of benefit to the Europeans. Had Hitler continued to develop nuclear capability and the ballistic missile technology exemplified by the V2 (the successor of which would have been intercontinental and was in prototype development when the development sites were overrun by allied forces), your predecessors might well have been waking up to a smouldering hole where New York used to be.

Britain and it's empire stood alone for the first two years of WWII, had we not done so, you'd be speaking German, so f00k you back.
