Hopkins had a major voice in policy for the vast $50 billion Lend-Lease program, especially regarding supplies, first for Britain and then, upon the German invasion, the Soviets. He went to Moscow in July 1941 to make personal contact with Joseph Stalin. Hopkins recommended and Roosevelt accepted the inclusion of the Soviets in Lend Lease. Hopkins made Lend Lease decisions in terms of Roosevelt's broad foreign policy goals. He accompanied Churchill to the Atlantic Conference. Hopkins promoted an aggressive war against Germany and successfully urged Roosevelt to use the Navy to protect convoys headed for Britain before the US had entered the war in December 1941. Roosevelt brought him along as advisor to his meetings with Churchill and Stalin at Cairo, Tehran, Casablanca in 1942-43, and Yalta in 1945. He was a firm supporter of China, which received Lend-Lease aid for its military and air force. Hopkins wielded more diplomatic power than the entire State Department. Hopkins helped identify and sponsor numerous potential leaders, including Dwight D. Eisenhower. He continued to live in the White House and saw the President more often than any other advisor.
