The United Kingdom did not aggress and was not aggressed upon. It's that simple.

It's just that it's not that simple. The british isles are a strategic possession, so even if the UK tried to make a point of neutrality during the war, it seems difficult to believe that nobody would attempt to occupy it. Plus, assuming that that's true, and no one invaded the UK, any nuclear strike in western europe would have affected the British Isles. Also, since it's not clear yet under what circumstances each country ended up after the war,how can we say that the pound sterling was the international reserve for currency?
