Input: Consider Input: In an effort to demonstrate peaceful intentions toward Germany, on 13 April 1941, the Soviets signed a neutrality pact with Axis power Japan. While Stalin had little faith in Japan's commitment to neutrality, he felt that the pact was important for its political symbolism, to reinforce a public affection for Germany. Stalin felt that there was a growing split in German circles about whether Germany should initiate a war with the Soviet Union. Stalin did not know that Hitler had been secretly discussing an invasion of the Soviet Union since summer 1940, and that Hitler had ordered his military in late 1940 to prepare for war in the east regardless of the parties' talks of a potential Soviet entry as a fourth Axis Power.

Output: Who was planning an invasion of the Soviet Union?

Input: Consider Input: On 1 September 1939, two days before Britain declared war on Germany, the station was taken off air with little warning; the government was concerned that the VHF transmissions would act as a beacon to enemy aircraft homing in on London. Also, many of the television service's technical staff and engineers would be needed for the war effort, in particular on the radar programme. The last programme transmitted was a Mickey Mouse cartoon, Mickey's Gala Premier (1933), which was followed by test transmissions; this account refuted the popular memory according to which broadcasting was suspended before the end of the cartoon.

Output: What did the British fear could provide guidance to the German air force?
