Looking at the World War I, the First World War brought many destruction and fear, and it has never been seen by the world so far. With the arrival of pain, the wave of change was seen after millions of people saw not only war but also life itself. As people were shown cruel and barbaric acts in connection with the First World War, the romanticism of protecting the country has completely disappeared.
Observing the origin of World War I will try to clarify the beginning of the Cold War by finding the origin of World War II and analyzing the conclusion of the latter. The origin of the First World War from 1914 to 1918 was mainly in two different geopolitical developments, the latter half of the 19th century and the early 20th century. The first of these was the unification of Germany after the period of relative peace after the Napoleonic War. In 1871, unification of Germany found a superiority of a single territory in the center of Europe.
In the 20th century, the two world wars were unexpected. Christopher Clark's highly appreciated "Dream Walker: European War of 1914 - a timely release of the First World War 100th Anniversary" - depicting an unexpected fall in Europe. Prior to World War I, it was a preamble to calm the relative peace and stability of the 19th century. Until the impact of the Holocaust comes out, the great European powers of the Edwardian era were engaged in diplomacy and trade. Since the major countries tried to avoid another war in the 1930s, submission policy was adopted and the United States initially did not want participation as well as the agreement between the Nazis and the Soviet Union. From this point of view, Neville Chamberlain will find out that there is more destiny of "Peace in our time". Through the Cold War, the concept of World War III was closely related to the doctrine of mutual guarantee and destruction of nuclear war and MAD.
