[Hey wait a minute,wasn't the Sandwich Islands discovered by that supreme navigator from Whitby,James Cook. He sheltered in a natural harbour and declared I name this place Pearl Harbour..........and Harbour it was and Harbour it is....honestly] My reference to Pearl Harbour as above was a tongue in cheek light hearted comment and I have no evidence that Cook sheltered in what became Pearl Harbour.However the fact is that James Cook discovered the Hawaiian Islands in January 1778 and declared I name these islands "The Sandwich Islands". This was a tribute to the 4th Earl of Sandwich who held the post of First Sea Lord during this era of the American wars of independence.Cook discovered these islands before the future of the British colony in America had been decided.(Earl Sandwich was also a gambler and sustained himself during long sessions at the gambling table with slices of bread and meat taken together.His mode of foodfare gave the English language,the sandwich.) The Sandwich Islands appears to have been the preferred name for the Hawaiian Islands until the middle of the 19th century. Getting back to Pearl Harbour,experience no matter what dimension, is usually drawn on by those who have to determine the outcome of new challenges...adverse experiences...stay clear or rectify/fine tune the response ....good and effective experiences...fine tune and probably template it.However along with the experience,an element of risk is introduced which can have short term or long term consequences. From that looking at the Japanese raid on Pearl Harbour,the Japanese are thought to have adapted the strategy utlised by the RN air raid at Taranto which crippled the Italian fleet on 11 November 1940.The RN were able to catch the Italian fleet at berth at the Taranto naval base. The Japanese raid was flawed to some extent by the lack of the overall intelligence picture.The Japanese took the risk and there would only one bite of the cherry, that the whole US Pacific fleet would be at anchor at Pearl Harbour.Fortunately the US carrier fleet was at sea and this would have long term consequences for theJapanese.As it was,the US naval/air victory over the Japanese at Midway during early June 1942 was the watershed of Japanese expansion in the Pacific.It would be a hard slog of island hopping to push the Japanese back to their homeland but nevertheless,the opportunity to overcome the Japanese due to their failure of the pre-emptive blow on Pearl Harbour must have been recognised by the US military leadership.With a superior developing technology and a high performing war economy,the US were able to deny Japan, the New Order for Asia that the Japanese military expansionists craved for. .
