Hmm, just to answer quickly. Yes it was wrong, and it was morally reprehensible, and it was "evil." But I think it was more an evil of disregarding the welfare of others than a positive evil, i.e. they weren't thinking that t they wanted to punish the Japanese people, they were just testing their new weapon.
If you read about the mulitary weapons industry, you will find that it is full of a sterile, distancing culture where the weapons are developed pretty much with only logistics in mind. What is important is how efficiently something can deliver a payload, what the fuel to distance ratio is, how big it makes America's national penis, not how will these effect the lives of people they are used on. So, it is not a personal evil, but a systemic evil that is encouraged and cultivate under the guise of national defense. It is in some ways less evil than murder, but in some ways far more insidious.
With that said, I'm not sure exactly what can be done about it. Changing and entire nation is difficult, especially if that nation sees no reason to change. If you're on top, why care about the little guys, right? That's the state of the world and of humanity, because it is how our collective Shadow manifests itself, and it probably always will be that way. Alas.
Edit: I'd like to point out that WWII wasn't really a high point in America's moral life. Look up
Unit 731 and note who granted them immunity and who actually prosecuted them.
As for the Mosque, the whole reaction to it is ridiculous. I'm just reminded of the Crusades and people being whipped up into an anti-Christian frenzy for no apparent reason, full of ignorance and ire. They had Pope Urban, we have Fox News and the Tea Party. I think what they, the "haves," are doing is irresponsibly nurturing the fear and xenophobia of uneducated, over-privileged mostly white Americans, for their own gain. It really sickens me, the apathy they have for other people; you would have thought they had learned to share their toys when they were younger (reproductive regulation? Yes, please), so sharing something as big as a nation wouldn't be so difficult. The doubletalk that is going on is insane, with probably a significant number of Americans believing something like the idea that Jesus himself established America as a haven for white people and Christians and that he said only rich people and wives who are doormats to their husbands can get into Heaven.
The fact of the matter is that the mosque is legal, it is in keeping with the true spirit of America, and people need to STFU and take a religion class. I swear, every time I turn on the news, I feel like I'm in bizarro world.

On a different topic. Aliens? Are they out there? UFOs, are they real? What about that Earth-like planet they found? Have they visited us before in ancient times? Why or why not?
