Государственный комитет обороны
At the outbreak of World War II, Voroshilov was held responsible for Soviet failures in Finland during the Winter War and was replaced as Defense Commissar by Semyon Timoshenko. Following the German invasion in June 1941, he was recalled and appointed to the State Defense Committee. Voroshilov failed to stop the German encirclement of Leningrad and was again relieved from his command in September 1941.
