It is estimated that 140 000 people died in Hiroshima from the American’s atomic bomb explosion and its consequences on the 6 of August. A similar estimate for Nagasaki is 74 000 people on the 9 of August. In addition, the city has undergone radioactive contamination. This radioactive contamination caused the death of a few hundred thousand people between 1950 and 1990. In both cities, the overwhelming majority of casualties were civilians, so that the instrument should rightly be regarded as a war crime and a particularly cynical violation of international conventions concerning the civilian population. Especially because there was no necessity of such impact, because Japan could not provide long-term resistance to the military power of the US and the USSR, and was on the verge of surrender.
Explosions of the American’s atomic bombs caused the destruction of the Japanese civilian population. By August 1945, about 60 Japanese cities had been destroyed during a large-scale air campaign, including the mass bombing of incendiary bombs in Tokyo (which killed about 100 000 people) and Kobe.
The United States declared that the bombing was something like psychological pressure on the Japanese government and helped end the war for months earlier than it would be without them, thus saving many lives that would have been lost on both sides, if there was a planned invasion by the Americans to Japan. However, the psychological impact still could drop bombs on military targets and not on civilians. And if this is justified by the first bomb, how to justify the second on Nagasaki? Most likely, the US objective was geopolitical: the psychological impact of this was provided for the entire MIP and especially to Stalin, that immediately after the Potsdam Conference to show that he is not the main godfather and must be compliant in postwar redistribution of the world.
Atomic bombs were created in the US in the so-called Manhattan Project on the initiative of Jewish scientists, including refugees from Europe (including - Albert Einstein), who feared that Germany is developing a nuclear weapon (as it turned out later, the Germans were quite far away from success). In fact, nuclear weapons and were intended for the complete destruction of Germany, but the war was over there earlier. More than 130 000 employees were implicated in the Manhattan project. This technology cost 2 billion dollars (over 22 billion dollars in today's prices). To date, it is the only combat use of nuclear weapons against the people.
