Re: Pearl Harbor
Japan, as an island nation, is resource limited. The war effort was consuming alot of those resources. As losses mounted they needed more resources to sustain the war effort. So, why not bomb/invade Hawaii to get those resources? Afterall, the US up to that point had simply sat on the sidelines and watched the war...well, other than shipping supplies to Britain, France, etc.
Call it Hubris (excessive pride) if you want but the Japanese thinking was that they could do this without drawing the US into the war. I forget who said it on the Japanese side but after the attack it was said that they had awoken the sleeping giant (or something very similar).
The other thinking that has been surfacing in recent years is that the US was wanting to get into the war but couldn't sway public opinion into actually doing something about the growing attrocities across the pond. What the US needed was something that would push the country into the war. Reports I've heard say that the US cracked the Japanese code well before Pearl Harbor and knew that Hawaii was being targetted. By not saying anything to Hawaii, the US code breakers didn't let on that they had broken the Japanese code and also provide the country with the necessary push to enter the war.
**I'm not saying this is right or wrong or trying to debate the moral implications that go along with this theory. Rather, just saying what's come out in recent years as another reason we've entered the war after this event.
Rest is history that hopefully we remember and don't repeat.
Of course this shouldn't diminish from the day that a number of lives were lost on both sides. A moment should be given to all that served that day and for those who continue serving as we are deeply indebted to the work that they do on a daily basis.
