Was the U.S. Right or Wrong Using the Atomic Bomb in "Hiroshima"

The history over few centuries shows that the Japanese never gave up, that they always choose "death" than "surrender". These two articles which I was studying very carefully, shows two opposite opinions about the necessity of using the atomic bomb to the end of World War II. Gar Alperowicz, in his article, "Hiroshima Remembered: The U.S. was Wrong", the evidence to prove that America didn't need to use atomic bomb on Hiroshima and Nagashaki to end the war. Contrary to this article John Connnor in his article "Hiroshima Remembered: The U.S. was Right" is trying to prove and convince reader that using atomic bomb on Hiroshima was necessary to end the war and it saved tremendous amount of American and Japanese lives. John Connor is using very emotional and very graphic language in his article. He called Japanese the "militarists" who are implacable, relentless enemies for "whom surrender was worse than death!" Their resistance was "savage" to the end in each battle they participate. As a proof of this, he mentioned the battle in Tarawa in 1943 where only 17 soldiers remain alive out of 5,000 soldiers "when the island was taken." Another example is the battle in Saipan where only one thousand soldiers of 32,000 defending Japanese survived; 10,000 civilians were killed, among them a lot of children. Japanese "bashed their babies' brains out of rocky cliff sides… children threw grenades at each other."17,000 Americans loose life in this battle. Another example is Okinawa where 110,000 Japanese soldiers and 100,000 civilians died. "Kamikaze alone cost American Navy 10,000 lives, and Army and Marine casualties were more than 50,000 soldiers. He is mentioning the fact that in 1945 American intelligence intercepts a message about Japanese desire for piece but this was "irrelevant because the Japanese government remained in the hands of militarists: Their message indicated a willingness to fight to the death." Japanese gathered 5,000 aircraft as suicide weapons.
