Nuclear Weapons
In its attempts to harness the power of the atom, mankind has itself in the possession of weapons with unbelievable, destructive power. Nations now have the ability to destroy entire cities from hundreds of miles away, in only minutes. These weapons are nuclear weapons. Nuclear weapons cost the citizens of the United States billions of dollars in taxes each year, the testing and maintenance of these weapons pose serious health risks, and the actual need for these weapons is not and has not been around for years. For the above reasons, I feel the United States should reduce its nuclear arsenal. Nuclear weapons derive their power from the energy released when a heavy nucleus is divided, called fission or when light nuclei are forced together, called fusion. In fission, a nucleus from a heavy element is bombarded with neutrons. The nucleus breaks into two pieces, releasing energy and two or more neutrons. Each of these neutrons has enough energy to split another heavy nucleus, allowing the process to repeat itself. This is the chain reaction that makes nuclear weapons possible. In a fusion nuclear device such as a hydrogen bomb, lightweight nuclei are forced to fuse at very high temperatures into heavier nuclei, releasing energy and a neutron. In order to squeeze the two nuclei together, an atomic fission bomb is usually used. A fusion reaction releases about four times more energy per unit mass than a fission reaction. The United States super...
