The "Cold War" is one of the most interesting "wars" fought in the history of the world. The sheer number of countries involved, both directly and indirectly, is enough to beg the question: to what extent was the Cold War a truly global war? This essay will examine this idea. It will identify two main areas of discussion, focusing on the first part of the conflict (1945-1963). Firstly it will examine the growing US and Soviet influence in the world after 1945. Secondly it will examine three major conflicts, the Berlin Blockade, the Korean War and the Cuban Missile Crisis in which these two superpowers were involved.

A good example of this would be World War I (1914-18). It was a conflict which, although taking place in Europe, involved countries such as New Zealand, Australia and the United States, all three countries located at a great distance from the actual conflict area. Since it involves much of the world, this would constitute a global war. Now that the idea of ​​global war has been established, it is important to establish the role of the United States (US). One of the most important documents in establishing this was the “Truman Doctrine.” President Harry S. Truman (1945-53) outlined what would become the basis of U.S. foreign policy throughout the Cold War.
