I had a meeting with American colleagues yesterday and I happened to mention that 'why we were having this meeting was ultimately because of Pearl Harbour'. Theyn looked at me askance, but one of them came up to me later and agreed with my general premise.
Hong Kong - yes - largely overshadowed by Pearl Harbour in historiography, but the occupation was nothing less than brutal, primarily because of visceral hatred of the Chinese. A little-know fact was that the surrender of Hong Kong was taken by a RAF Flt Lt - of the Works Branch.
