Question: was the soviet union a member of the axis powers

Answer: No, On January 17, 1941, seven days after the German--Soviet Border and Commercial Agreement, Molotov asked German officials whether the parties could then work out an agreement for entry into the Axis pact. Molotov expressed astonishment at the absence of any answer to the Soviets' November 25 offer to join the Pact. They never received an answer. On March 1, 1941, Bulgaria joined the Axis, which further unsettled Stalin when combined with Germany's continued ignoring of Stalin's November 25, 1940 Axis entry proposal. After six months of preparations, Germany invaded the Soviet Union on 22 June 1941, ending any hope for the proposed alliance.
