• "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. The first fission bomb test released the same amount of energy as approximately 20,000 tons of tnt.
  • Atomic_Bomb_freecomputerdesktopwallpaper_1600.jpgThe first thermonuclear bomb test released the same amount of energy as approximately 10,000,000 tons of TNT. A modern thermonuclear weapon weighing little more than 2,400 pounds can produce an explosive force comparable to the detonation of more than 1.2 million tons of TNT. Thus, even a small nuclear device no larger than traditional bombs can devastate an entire city by blast, fire and radiation.

  • Nuclear weapons are considered weapons of mass destruction, and their use and controll has been a major focus of international relations policy since their debut. In the history of warfare, only two nuclear weapons have been detonated offensively, both near the end of world war II.The first was detonated on the morning of 6 August 1945, when the United states dropped a urainium gun-type device code-named "Little boy" on the Japanese city of Hiroshima.The second was detonated three days later when the United States dropped a plutonium implosion-type device code-named "fat man" on the city of Nagasaki ,Japan.These two bombings had the result of 200,000 deaths. this is only a test.

Within the first two to four months of the bombings, the acute effects killed 90,000–166,000 people in Hiroshima and 60,000–80,000 in Nagasaki with roughly half of the deaths in each city occurring on the first day. The Hiroshima prefectural health department estimates that, of the people who died on the day of the explosion, 60% died from flash or flame burns, 30% from falling debris and 10% from other causes. During the following months, large numbers died from the effect of burns, radiation sickness, and other injuries, compounded by illness. In a US estimate of the total immediate and short term cause of death, 15–20% died from radiation sickness, 20–30% from flash burns, and 50–60% from other injuries, compounded by illness. In both cities, most of the dead were civilians.n 1950, the U.S. government adopted a new cornerstone of its foreign policy based on the finding that the Soviet Union was likely to launch a surprise attack on us "once it has sufficient atomic capacity." That assessment was included in a National Secutiry Council document known as NSC-68. Defense spending was increased by 350 percent. But, the roots of the cold war actually go back to World War II and its aftermath.
When World War II ended, the "hot war" of bombs and bullets became a "cold war" of speeches and threats. After the war, there were only two super powers, the United States and the Soviet Union, with completely different political systems. These countries had been on the same side during the hot war. But in the cold war, they were enemies.

What made this war of words more tense than ever before was the fact that both countries had enough atomic bombs to destroy much of the world. Many of the key military bases of the cold war were located in Nebraska and the Central Plains. So, those who lived here during the 1950s and 60s were very aware that there were nuclear bombs pointed at them all the time.
So, what happened far away in Europe and the world had a big impact and interest for those living in Nebraska and the Plains.

The initial focus of the Cold War was in Eastern Europe where the Soviet Union was setting up communist governments to provide a buffer against the West. Former Prime Minister Winston Churchill of Great Britain was speaking in Fulton, Missouri, in 1946, when he said:

  • nuclear_sign.jpg"It is my duty to place before you certain facts about the present position in Europe. From Stettin in the Baltic to Trieste in the Adriatic, an iron curtain has descended across the Continent. Behind that line lie all the capitals of the ancient states of Central and Eastern Europe ... and the populations around them lie in what I must call the Soviet sphere, and all are subject, in one form or another, not only to Soviet influence but to a very high and in some cases increasing measure of control from Moscow.Churchill's speech got a positive response from the American people. In their judgement, "Americans really listen to Mr. Churchill and there is little doubt that the speech will set the pattern of discussion on world affairs for some time to come." Churchill's image of an Iron Curtain became a powerful political symbol of the Cold War.In response to the Soviet Union's policies, the United States government developed the policy of "containment." The U.S. goal was to contain communism and not allow that political system to be adopted in other parts of the world. The United States negotiated a series of alliances with non-communist nations. In those alliances, the U.S. promised to protect those nations . . . with force and atomic weapons if necessary. And that fact made many in the world, and in Nebraska, nervous.This section will explore the impact of the atomic bomb on life in Nebraska, the fear of communism, the build up of military bases in Nebraska, and the attempts to defend the civilian population in the Plains.
