what was germany's plan for fighting a two-front war
Two-front war During World War I, Germany under Kaiser Wilhelm II fought a two-front war against French, British, Belgian, and (later) American forces on the Western Front while simultaneously fighting the Russians on the Eastern Front. Russiaâ€™s participation ended in the First World War, when the Bolshevik leaders signed the Treaty of Brest-Litovsk with Germany in March 1918. Germany had foreseen such a scenario, and developed the Schlieffen Plan in order to counteract being surrounded by its enemies.[citation needed] Under the Schlieffen Plan, German forces would invade France via Belgium, Luxembourg, and the Netherlands (the idea to go through the Netherlands was abandoned because of the country's neutrality), quickly capturing Paris and forcing France to sue for peace. The Germans would then turn their attention to Russia in the east before the Tsar could mobilize his massive forces. Due to several factors however, the Germans failed to achieve the plan's aims.
World War II The Empire of Japan aimed to dominate Asia and the Pacific and was already at war with the Republic of China in 1937,[5] but the world war is generally said to have begun on 1 September 1939[6] with the invasion of Poland by Nazi Germany and subsequent declarations of war on Germany by France and the United Kingdom. Supplied by the Soviet Union, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. The war continued primarily between the European Axis powers and the coalition of the United Kingdom and the British Commonwealth, with campaigns including the North Africa and East Africa campaigns, the aerial Battle of Britain, the Blitz bombing campaign, and the Balkan Campaign, as well as the long-running Battle of the Atlantic. On 22 June 1941, the European Axis powers launched an invasion of the Soviet Union, opening the largest land theatre of war in history, which trapped the major part of the Axis military forces into a war of attrition. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific.
