Seeing as I grew up on a military base, I don't see the need to ask a soldier. LOL I have seen their kindness and cruelty on both hands. Believe me when I say this, inappropriate behavior is not acceptable to the citizens of the US.
Actually, that was not the US but the Axis powers... and with good reason. They jumped into the war with no provocation to seize an opportunity under the orders of their then Emperor (for the life of me I can't remember his name. I think it started with an S). After the war, the UN's judgement (there were trials and such, I think between 4 and 5 hundred of them) was that Japan was to be divided between the US and Russia and the Japanese people adopted a new form of government and wrote their constitution. This constitution eliminated all power from the Emperor and the title became nothing more then a symbol. In 1972 the US released their territories back into the hands of the Japanese people, Russia held on longer to theirs... can't remember when.
During the time that the US occupied Japan, they rebuilt everything that was destroyed and adding funding to various programs for Japan and its people. Why do you think that Japan and the US have such close ties now? The US became their biggest buyer for technologies and Japan became a technological power house (what is it with the Asian countries and their technology... LOL).
The current Japanese constitution followed the guidelines of the US' but it was their people who decided, not the US. If the US is who made it and they were so bad to the Japanese and such... then the Japanese would not hold such close ties with the US and still hold the Constitution from then? The Japanese have their self defense army even though they were denied by the Axis countries of having an Army because the US encouraged them to have one and plied for their right to have one. The US did not want to occupy Japan for long, that is why they left only a few years after the war ended. They in fact never wanted to occupy any nation over seas.
We are no Angels, but we are not the bad guys. In fact, we did not even want to get involved in either WWI or WWII. The US was dragged into WWI kicking and screaming and tried their best to stay out of the war. WWII they attempted to stay out until Hitler started going overboard and began slaughtering the Jews. The US then jumped in willingly to stop Hitler.... and that is when the Japanese attacked the US. Should the US have bombed Japan the way they did? Heck no, you ask anyone here and they will tell you it was a shameful moment in US history. It was overkill and the cost of innocent lives for the sake of revenge was intolerable. However, the past is the past... it can not be changed. All that happen is to move forward to a brighter future.
