Do you agree with the decision of the United States to drop atomic bombs on Japanese cities?

I think that each country or the world would like to pursue a foreign policy that would ensure the safeguard of its interests. But it depends on the world stature of a country to act upon such a policy. America has been a world power for around a century. In case of Japan in World War II, America wanted to establish itself as a world power. Japan had been a great threat that was resisting during the war and the war had been elongating. To a theoretically degree, I think that America had to drop the atomic bombs as it had run out of options. Many may not agree to my personal opinion of considering the dropping the atomic bomb as a reason that stopped the war otherwise it might have been going on for a longer period and would have had much more devastating results for human race that the dropping of the atomic bombs at Japanese cities.
