How did japan join world war 2?

Answer 1

Foreign minister Ribbentrop attempted to reverse his pressure on Japan of the previous year to attack Singapore, which Japan had so far resisted. Now he wanted Japan to attack the Soviet Union, a complete u-turn on Germany's previous request that Japan improve its relations with Moscow. However, much of Japanese leadership were angered by this German inconsistency and apparent lack of respect for its Japanese ally, so they proceeded south instead. Here Japan shows a resistance to external pressure from Germany because its interests lay elsewhere. The cabinets decision in July 1941 to acquire bases in Indochina preparatory to a strike against Singapore and the East Indies reflected the confluence of strategic opinoon in the two services, now the Russian threat was lessened. This plan had the advantage of appearing to be a response to German requests pre June, while at the same time making it impossible for Japan to meet the new German demands to attack Russia. This shows that from 1937 - 1941 Russian neutrality and its preoccupation with Germany was an important factor in uniting the two services and in Japanese expansion into Southeast Asia later in the year. However it also shows Japan had a clear agenda of its own, and did not submit to external pressure from Germany to open a 2nd front with Russia, but continued with its expansion Southward. After the war in Europe broke out, Pres. Rossevelt assigned priority to the overthrow of Nazi Germany, guiding American world strategy by the simple logic that Germany's friends were Americas enemies. When Japan befriended the "Nazi devils" American opinion grew much more hostile. However, Hosoya Chihiro argues that the Tripartite Pact was not an attempt by Japan to establish links with the fascist powers to challenge the U.S., but means of ending Japans worrying isolation and simply deterring American interference in the Far East, even as a preliminary to an improvement in Tokyo-Washington relations. Therefore, at this stage, Japan still believed the external threat of the United States. Here is another take: Causes of the war can be traced back to the end of WW1 and a depressed world economy which preceeded the American Depression of the 1930's. Germany, Italy, and Japan suffered deep economic problems. Inflation was rampant. However, by the late 1920, economic order was being restored. This trend revered when the U.S. entered the Great Depression. The world economic situation sent country after country into crisis. This gave rise to an isolationist stance on behalf of the U.S.; and a Nationalistic view across most of the globe. The citizens of what would be THE AXIS POWER (GERMANY, ITALY, AND JAPAN) supported nationalistic organizations which offered hope in the face of these problems. These organizations soon gave birth to tyranny and Dictatorship. Totalitarian dictatorships arose in the Soviet Union, Italy and Germany. In Japan; the Royal Thron submitted to militarism. These despotic governments were led by Josef Stalin, Emperor Hirohito and Tojo, Benito Mussolini and Adolf Hitler, respectively. These leaders seized power by promising reform through unity. Under the dictatorships, however, terror reigned. Dictators used secret police, threats, imprisonment and even executions to eliminate their opposition. In Japan the Japanese were called on to die for their country and their emporeror in fanatic suicide pacts. Some consider the state of WW2 to be Japan's invasion of Manchuria, a region in eastern China. Japan continued to demonstate aggression, effectively conquering eastern China by 1938. Early in the conflict the Japanese attacked and sun the USS Panay; some suppose as an effort to draw America into the conflict, but the US stood aside and watched in horror as Japan raped, pillaged and murdered its way through China. America was still absorbed in isolationism.
