World War 2 which has started in 1939 was the most devastating war the world has ever fought. One of the reasons for that devastation was because the Third Reich forces used a tactic called Blitzkrieg which was designed the following way: At first Dive Bombers went in to strike enemy points (JU-87 Stukas) were the most popular for those missions. After the bombardment went the Wehrmacht (tank) forces and the Infantry. The other devastating problem for the Allies was the new Submarine tactics. Hitlers engineers have developed a submarine known as a U-Boat. Those were mostly used for the blockade of Great Britain to sink allied shipping. The most devastating moment of the war was in 1945 when the United States launched a successful Atomic strike in Hiroshima and Nagasaki causing more then 200,000 casualties from each atomic bomb. In total 75,000,000 people died as the result of battles.
The Cold War started because of United States and Soviet Unions difference in view when it comes to Communism. US became more and more concerned with how the Soviet Union are showing their "expansive tendencies" when it comes to their dealings with Europe. The long telegram that was sent to the Department of State became the greatest foundation of the America's Cold War Policy of containment.
The Soviet Unions aggressive speeches and actions against Iran and Turkey gave way to the Truman's administration to show a stronger stance instead of a diplomatic approach that the previous administrations were doing. These factors guaranteed acceptance of Kennan's analysis that was expressed on the telegram.
