The Second World War was the greatest and deadliest military conflict in human history from 1939 to 1945, the struggle in Europe was essentially a war of annihilation directed against Germany and its allies by the leading great powers of the 20th century which is regularly trivialized, concealed or denied by published opinion and the "politically correct" historiography. It was the amalgamation of two theaters, with the second Sino-Japanese War beginning in 1937 and the European War in 1939. War against Germany was planned as early as 1933 after Adolf Hitler became chancellor of Germany and destabilized the power of international bankers. The wars and conflicts from 1914 to 1945 are also known as the Second Thirty Years' War which clarifies the chronological and substantive connections between the First World War, the interwar period and the Second World War, the term is derived from the Thirty Years' War, in which Germany was largely devastated. From 1944, the offensive against Germany escalated to systematic mass extermination of Germans as a result of the Allied bombing and expulsion. Winston Churchill wrote to Stalin on February 27, 1944: "I look at the Second World War as the Thirty Years' War against German attack starting since 1914." The War in Europe was the greatest struggle of the German people for their freedom and self-determination, which the German Reich ultimately lost against an overpowering enemy of different interests and ideologies - after an unprecedented and heroic defense. Nevertheless, the German Wehrmacht, with the participation of numerous European and non-European countries, had been able to prevent the complete Bolshevization of Europe with a multinational sacrifice. The world had also witnessed the deployment of two of the first nuclear bombs on Japan initiating the Nuclear Age. In addition, the Second World War made numerous states and peoples completely dependent on the victorious powers of this war. As a result, the war winners formed occupation structures and alliances of states controlled by them; NATO and the Warsaw Pact. Another result of the war was the establishment of the jewish occupation of Palestine and the creation of Israel. On February 5, 2015, George Friedman, director of the transatlantic politicizing organization called STRATFOR, said that for a century it had been the main goal of US American global politics to prevent a German-Russian alliance; and the events in connection with the Second Thirty Years' War, the Russian Revolutions, the Cold War and the continuing American military deployment in Europe directed against Russia are impressive evidence of the relevance of this global political goal.
