Terms that were un-necessary. Japan still has an emperor no? Could have ended the war much earlier if they wanted to.
And another factor is that we haven't had a nuclear war since Japan, which showed the horrors of nuclear warfare. Had that not happened, maybe real nuclear weapons would have been used by someone later on, when they were much more powerful and more numerous, and even when both sides possessed them? The bombings have helped ensure that something much worse hasn't happened since.
And you know what, the Japanese government deserved it. They started the war, killed millions of people in the process (including many millions of civilians in Asia), and then had the gall to try to bargain for decent surrender terms after all that horror they caused? Nope. Sometimes harsh punishment is necessary.
The government yes. The people did not elect them. They had no choice in the matter, and were also trained into full propaganda mode many years before the war. So targeting civilians with fire-bombing is certainly questionable. Even McNamara said that what they did in Japan would be considered "crimes of war" in case they did not end up victorious.
No matter which way a leader comes to power, the population pays the taxes and the ultimate tolls.
This means that when we are on the inside, in the country, we can't be more or less complacent with a bad dictator than a bad elected leader, we always pay the price for what they do. It's always our problem.
Applying that standard, there would not be a single American left alive for the constant war they wage since the end of WW2.
In warfare more than almost anything else, might matters.
Wonder what you have to say about what the US deserves after the Iraq war?
