Which of the quotes below supports the following thesis statement?

The dropping of the atomic bombs on Hiroshima and Nagasaki prior to the end of WWII was necessary to end the war in the Pacific quickly.

A. "....the enemy now possesses a new and terrible weapon with the power to destroy many innocent lives and do incalculable [huge] damage. Should we continue to fight, not only would it result in the ultimate collapse and obliteration [destruction] of the Japanese nation, but it would also lead to the total extinction of human civilization."

Quote by Emperor Hirohito, 1945 (Japan)

B. The use of (the atomic bombs) at Hiroshima and Nagasaki was of no material assistance in our war against Japan. The Japanese were already defeated and ready to surrender because of the effective sea blockade and the successful bombing with conventional weapons...."

Quote by Fleet Admiral William D. Leahy, 1950 (U.S.A)

C. "I realized that [Stalin and Churchill] were talking about research on the atomic bomb. It was clear already then that the U.S. government intended to use the atomic weapon for the purpose of achieving its imperialist goals...in the 'cold war'...Without any military need whatsoever, the Americans dropped two atomic bombs on the peaceful and densely-populated Japanese cities of Hiroshima and Nagasaki.

Quote by Marshal Georgii Zhukov, 1971 (U.S.S.R)

D. "There are voices which assert that the bomb should never have been used at all. I cannot associate myself with such ideas...I am surprised that very worthy people...should adopt the position that rather than throw this bomb, we should have sacrificed a million American and a quarter of a million British lives...."

Quote by Winston Churchill, 1945 (U.K.)
