Turkey's goal was to maintain neutrality during World War II. Ambassadors from the Axis powers and Allies intermingled in Ankara. İnönü signed a non-aggression treaty with Nazi Germany on 18 June 1941, 4 days before the Axis powers invaded the Soviet Union. Nationalist magazines Bozrukat and Chinar Altu called for the declaration of war against the Soviet Union and Greece. In July 1942, Bozrukat published a map of Greater Turkey, which included Soviet controlled Caucasus and central Asian republics. In the summer of 1942, Turkish high command considered war with the Soviet Union almost unavoidable. An operation was planned, with Baku being the initial target. Turkey traded with both sides and purchased arms from both sides. The Allies tried to stop German purchases of chrome (used in making better steel). Inflation was high as prices doubled. By August 1944, the Axis was clearly losing the war and Turkey broke off relations. Only in February 1945, Turkey declared war on Germany and Japan, a symbolic move that allowed Turkey to join the future United Nations.
