More than 500 million people have died from infectious diseases over the past century. Some of these deaths were caused by deliberate attempts by the enemy, and many of these deaths occurred during times of war. Biological warfare dates back to 1346, when it was also known as germ or bacteriological warfare. It is defined by the United Nations as the use of any living organism or effective component to cause disease or death in humans, animals or plants. (Stebbins, 2007) This type of attack was used in several cases, such as during the siege of Caffa, a town in present-day Crimea, when plague-infected corpses were thrown toward enemy front lines. During World War I, when horses and cattle were injected with snot and anthrax. World War II, when the Japanese conducted plague experiments without regard for others. Several other cases have also been reported as strategies used by the enemy aside from those mentioned, such as putting corpses in water supplies, spreading insects on food supplies, and the countless allegations made during the Korean War against the United States by the Soviets. The Korean War began on June 25, 1950 when conflict broke out at the 38th parallel, the border that divided the country in two. This invasion and declaration of war was the first military act of the Cold War. It began as a civil war between the North and the South, in part because each side wanted to rule differently. Kim II Sung wanted a communist government in North Korea and Syngman Rhee, the first president of South Korea opposed this dictatorship. The war between the North and South lasted only two days before other parties became involved. The United States ...... middle of paper ...... there for something big. Works cited (2005). J.
