War in the Pacific: Important Battles By early-1942, it became difficult for Japanese to maintain control of vast empire switch to defensive! Low on resources and weapons U.S. codebreakers discovered several planned attacks Once a 2ndfront in Europe is opened (Spring of 1942), American forces concentrated on island hopping: a military strategy of attacking specific enemy-held islands. Battle of the Coral Sea: (5/4/1942) mutual bombing of navies Battle of Midway: (6/4/1942) U.S. wins its first Pacific battle by fighting from the air and destroying the Japanese navy.

DISCUSSION THINKER: In your opinion, which Pacific battle was the most important in the defeat of Japan? Why? Explain!
Allied Bombing Campaign By Spring 1945, Japanese home islands were in range of US B- 29 bombers. US Air Force decided to attack at low level with incendiary bombs. Civilian deaths = 300,000 and of country s urban centers were burned to the ground Japanese government still refused to surrender.
HOMEWORK: Due tomorrow! Read about the Manhattan Project! Finish the Manhattan Project portion of the worksheet Be prepared to develop and defend your personal opinion on the atomic bomb!
Bellwork 10/1: Analyze the pros/cons of the atomic bomb. PRO BOMB! ANTI BOMB!
The Manhattan Project A 1941 top secret plan to develop the first atomic bomb. Combination of scientists and physicists Albert Einstein Robert Oppenheimer Presidential approval FDR Truman How it works . https://www.youtube.com/watch?v=E-Ks-Bs0MPM
File:Trinity shot color.jpg Atomic bomb test: Los Alamos, New Mexico July 1945
Trumans decision Truman warned Japanese that if they didn t surrender, they could expect a rain of ruin from the air Enola Gay dropped the first atomic bomb on Hiroshima on August 6, 1945 The second was dropped on Nagasaki on August 9, 1945
Civilian Warning Pre-Hiroshima TO THE JAPANESE PEOPLE: America asks that you take immediate heed of what we say on this leaflet. We are in possession of the most destructive explosive ever devised by man. A single one of our newly developed atomic bombs is actually the equivalent in explosive power to what 2000 of our giant B-29s can carry on a single mission. This awful fact is one for you to ponder and we solemnly assure you it is grimly accurate. We urge that you accept these consequences and begin the work of building a new, better and peace-loving Japan. You should take steps now to cease military resistance. Otherwise, we shall resolutely employ this bomb and all our other superior weapons to promptly and forcefully end the war.
Civilian Warning Pre-Nagasaki ATTENTION JAPANESE PEOPLE. EVACUATE YOUR CITIES. Because your military leaders have rejected the surrender declaration, two momentous events have occurred in the last few days. The Soviet Union, because of this rejection on the part of the military has notified your Ambassador Sato that it has declared war on your nation. Thus, all powerful countries of the world are now at war with you. Also, because of your leaders' refusal to accept the surrender declaration that would enable Japan to honorably end this useless war, we have employed our atomic bomb. A single one of our newly developed atomic bombs is actually the equivalent in explosive power to what 2000 of our giant B-29s could have carried on a single mission. Radio Tokyo has told you that with the first use of this weapon of total destruction, Hiroshima was virtually destroyed. Before we use this bomb again and again to destroy every resource of the military by which they are prolonging this useless war, petition the emperor now to end the war. Our president has outlined for you the thirteen consequences of an honorable surrender. We urge that you accept these consequences and begin the work of building a new, better, and peace-loving Japan. Act at once or we shall resolutely employ this bomb and all our other superior weapons to promptly and forcefully end the war. EVACUATE YOUR CITIES.
Aftermath Ground Temperature 7000F Force Winds 980mph Energy Released 20,000 tons of TNT Buildings Destroyed 62,000 Killed Immediately 80,000 people Dead by end of 1945 140,000 people Total Deaths 220,000 people

Review: Superpowers post-WWII Why did the U.S. and U.S.S.R emerge as superpowers post-WWII? Military Reasons US #1 air power & USSR #1 ground forces; FR/UK could not defeat Germany, USSR lacking strong neighbors regional power! Economic Reasons Both economies strengthened by war, US committed to open trade, E.Euro needs a larger/dependable power Political Reasons Both see democracy/communism triumphing over fascism, USSR resisted Germany, Stalin s influence in Europe, USSR/US strength prevented instability in their spheres of influence Areas of tension Post-war control of Poland, Germany, E.Europe and Japan; China, formation of the UN, reparations, atomic bomb, elections
Yalta Conference February 1945 Roosevelt, Churchill, and Stalin met at Yalta (Soviet Union) to discuss the postwar world Formed the United Nations Divided Germany and Berlin into four zones Stalin obtained Poland if he promised to allow free elections Stalin gained Pacific islands if he promised to declare war on Japan
KEEP IN MIND: Stalin is gong to break these promises .. COLD WAR!!!!
