Task: Question Generation
Input (English): Allies of World War II -- In March 1939, Germany took over Czechoslovakia, violating the Munich Agreement signed six months before, and demonstrating that the appeasement policy was a failure. Britain and France decided that Hitler had no intention to uphold diplomatic agreements and responded by preparing for war. On 31 March 1939, Britain formed the Anglo-Polish military alliance in an effort to avert a German attack on the country. Also, the French had a long-standing alliance with Poland since 1921. The Soviet Union sought an alliance with the western powers, but Hitler ended the risk of a war with Stalin by signing the Nazi--Soviet non-aggression pact in August 1939. The agreement secretly divided the independent nations of Eastern Europe between the two powers and assured adequate oil supplies for the German war machine. On 1 September 1939, Germany invaded Poland; two days later Britain and France declared war on Germany. Then, on 17 September 1939, the Soviet Union invaded Poland from the east. A Polish government-in-exile was set up and it continued to be one of the Allies, a model followed by other occupied countries. After a quiet winter, Germany in April 1940 invaded and quickly defeated Denmark, Norway, Belgium, the Netherlands and France. Britain and its Empire stood alone against Hitler and Mussolini. In June 1941, Hitler broke the non-aggression agreement with Stalin and Germany invaded the Soviet Union. In December, Japan attacked the US and Britain. The main lines of World War II had formed.
