Nuclear Disasters And History of Wars

World War I (WWI or WW1), also known as the First World War, or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by grueling trench warfare. It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved.

The war drew in all the world's economic great powers, assembled in two opposing alliances: the Allies (based on the Triple Entente of the British Empire, France and the Russian Empire) versus the Central Powers of Germany and Austria-Hungary. Although Italy was a member of the Triple Alliance alongside Germany and Austria-Hungary, it did not join the Central Powers, as Austria-Hungary had taken the offensive, against the terms of the alliance.  These alliances were reorganized and expanded as more nations entered the war: Italy, Japan and the United States joined the Allies, while the Ottoman Empire and Bulgaria joined the Central Powers.

The American Civil War was a civil war in the United States fought from 1861 to 1865. The Union faced secessionists in eleven Southern states grouped together as the Confederate States of America. The Union won the war, which remains the bloodiest in U.S. history.Among the 34 U.S. states in January 1861, seven Southern slave states individually declared theirsecession from the U.S. and formed the Confederate States of America. War broke out in April 1861 when they attacked a U.S. fortress, Fort Sumter. The Confederacy grew to include eleven states; it claimed two more states and several western territories. The Confederacy was never diplomatically recognized by any foreign country. The states that remained loyal including border states where slavery was legal, were known as the Union or the North. The war ended with the surrender of all the Confederate armies and the collapse of Confederate government in spring 1865.

The Gulf War (2 August 1990 – 28 February 1991), code named Operation Desert Shield (2 August 1990 – 17 January 1991) for operations leading to the buildup of troops and defense of Saudi Arabia and Operation Desert Storm (17 January 1991 – 28 February 1991) in its combat phase, was a war waged by coalition forces from 34 nations led by the United States against Iraq in response to Iraq's invasion and annexation of Kuwait.

The war is also known under other names, such as the Persian Gulf War, First Gulf War, Gulf War I, Kuwait War, First Iraq War, or Iraq War before the term "Iraq War" became identified instead with the 2003 Iraq War (also referred to in the US as "Operation Iraqi Freedom"). The Iraqi Army's occupation of Kuwait that began 2 August 1990 was met with international condemnation, and brought immediate economic sanctions against Iraq by members of the UN Security Council. US President George H. W. Bush deployed US forces into Saudi Arabia, and urged other countries to send their own forces to the scene. An array of nations joined the Coalition, the largest military alliance since World War II. The great majority of the Coalition's military forces were from the US, with Saudi Arabia, the United Kingdom, and Egypt as leading contributors, in that order. Kuwait and Saudi Arabia paid around US $32 billion of the US $60 billion cost.
