Honestly there is no reason they shouldn't have. If they did not, there would have been a costly invasion of mainland Japan. And the war would have continued on and a lot more people would have been killed.
Based on the information available to the US Gov't at the time? Yes. Because, to the best of the knowledge of the US Gov't and Military, Japan would never surrender and a full-scale invasion of the Japanese mainland would be the only way (other than the Manhatten Project) to end the war - which was expected to cost more than 1 million lives.
Base in the information that we know now? Nope. Japan was attempting to surrender, but their mistake was using Russia as the intermediary. The problem was that Russia wanted to conquer Japan, so it was in their interests to let the war drag on to weaken the Japanese military even more.
As they say, hind-sight is 20/20. It is too easy to be a Monday-morning quarterback, and much to difficult to be the ones making the hard decision. But a decision needed to be made, and the right one was made based on the information and intelligence that was available to the decision-makers.
Since Japan has done nothing to antagonize us since the 40s when we dropped a nuke the first time, NO! Definitely not. If you're asking whether should ever have, then that's debatable and there is no concrete answer I can give.
No. Whether or not we should have used the nuclear weapons during WWII is one debate, but there is no reason for us to attack Japan now in any way. We are close allies.
No, they did not.
Two were dropped on Japan to end WW2.
no only blacks did no the US dropped 2 on Japan. Japan has never had nuclear weapons.
Dropped on Japan to end the war.
At end of world war two, two were dropped in Japan, which ended the japan - America conflict
the u.s. used non nuclear weapons and nuclear weapons against japan
Japan has no nuclear weapons.
By 'us' I assume you mean the USA. Japan did not threaten anyone with nuclear weapons, it was only the USA who had them. The Japanese capitulated after the USA dropped atomic bombs on Hiroshima and Nagasaki.
The only country to ever use nuclear weapons in war is the United States with the two bombs they dropped on Japan. No other country has ever actually used a nuclear weapon.
Japan has nuclear power plants but no nuclear weapons
None. Nuclear weapons have not been, nor are likely to, authorized for use.
after the atomic bomb was dropped on japan 2 times nuclear weapons were band from being used in war.
