Transcript of Lozano Presentation

The effects of the war differed in different countries.
-The area that felt the full force of the bomb has been turned into a Peace Memorial Park with gardens of great beauty and almost 40 memorials to the victims of the atomic bomb attack.
-Hiroshima is known as the International City of Peace and is dedicated to the ban of the total use of atomic weapons.
-Here is picture of the fall of Berlin. The relentless destruction was responsible of one man named Hitler.
The brutal power of twenty armies, 6,000 tanks and 8,000 air crafts, all with the objective of crushing the German resistance and capturing Berlin.
- The Manhattan Project was committed to expediting research that would produce a viable atomic bomb.
-Einstein and several other scientists told Roosevelt to purify uranium-235, which could be used to create an atomic bomb.
-The Manhattan Project was a research and development program by the United States with the United Kingdom and Canada that produced the first atomic bomb during World War II.
- It was also charged with gathering intelligence on the German nuclear energy project.
Over 90% of the cost was for building factories and producing the fissionable materials.
-Two types of atomic bombs were created to be used during the war.
-On August 6, 1945, the United States used a massive, atomic weapon against Hiroshima, Japan.
While Japan was still trying to comprehend this devastation, three days later the United States struck again, this time on Nagasaki.
The military history of the United States during World War II covers the war against Japan, Germany and Italy starting with the December 7,1941 attack on Pearl Harbor.
- Key civilian advisers to President Franklin D. Roosevelt included Secretary of War, Henry Stimson, who mobilized the nation's industries and induction centers to supply the Army, commanded by Gen. George C. Marshall and the Air Force under Gen.
-A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter.
-A modern thermonuclear weapon weighing little more than 2,400 pounds (1,100 kg) can produce an explosive force comparable to the detonation of more than 1.2 million tons (1.1 million tonnes) of TNT.
-On 6 August 1945, a uranium gun-type fission bomb code-named "Little Boy" was detonated over the Japanese city of Hiroshima.
-Three days later, on August 9, a plutonium implosion-type fission bomb code-named "Fat Man" was exploded over Nagasaki, Japan.

-Since the bombings of Hiroshima and Nagasaki, nuclear weapons have been detonated on over two thousand occasions for testing purposes and demonstrations.
-The Federation of American Scientists estimates there are more than 19,000 nuclear warheads in the world as of 2012, with around 4,400 of them kept in "operational" status, ready for use.
-The only countries known to have detonated nuclear weapons—and that acknowledge possessing such weapons—are the United States, the Soviet Union , the United Kingdom, France, the People's Republic of China, India, Pakistan, and North Korea.
-Though the central strategic principle governing allocation of resources to the two fronts provided for concentrating first on the defeat of the European Axis, on the American side this principle was liberally interpreted, permitting conduct of an offensive war against Japan as well as against Germany in the years 1943-45.
-Development that the Japanese had not anticipated when they launched their attack on Pearl Harbor.
-The U.S. Fleet expanded after its initial setback at Pearl Harbor much as the Army had provided the main sinews for an offensive strategy in the Pacific.
-The U.S. provided millions of dollars in weapons, armament as well as money itself to the Allied forces.Then after Japan bombed Pearl Harbor they joined the Allies.
-World War II began on September 1,1939 when Germany attacked Poland without a formal declaration of war. In support of their mutual defense treaty obligations with Poland, France and Great Britain issued ultimatums to Hitler for the immediate withdrawal of German forces from Poland.
-An atomic bomb is an explosive device that releases nuclear energy. All previous explosive devices were powered by rapid burning or decomposition of a chemical compound.
-Nuclear explosives are energized by splitting an atom, a process called fission.
-On July 16, 1945 the first atomic bomb was detonated at 5:30 a.m. The resulting implosion initiated a chain reaction of nearly 60 fission generations in about a micro-second.
- The start of Pearl Harbor began just before 8 on the morning of December 7, 1941.
-The barrage lasted just two hours, but it was devastating: The Japanese managed to destroy nearly 20 American naval vessels, including eight enormous battleships, and almost 200 airplanes.
-The day after the assault, President Franklin D. Roosevelt asked Congress to declare war on Japan; Congress approved his declaration with just one dissenting vote.
-Three days later, Japanese allies Germany and Italy also declared war on the United States, and again Congress reciprocated.
-More than two years into the conflict, America had finally joined World War II.

World War II
-World War II finally ended when the Allied forces had successfully defeated the Germans in the battle.
-It was just the first turning point,but the very event that really made the war end was when the US Bomber plane bombed the the two cities: Nagasaki and Hiroshima, which led the Japanese to surrender unconditionally.
