84 years ago today, on January 6, 1941 (December 9, 1940), President Roosevelt submitted the Lend-Lease Act to Congress. The US Senate is discussing the Lend-Lease Act. On January 6, 1941, President Roosevelt introduced the Enhanced American Defense Act to Congress, the Lend-Lease Act. After two months of intense debate, the two houses voted separately. On March 11, President Roosevelt signed the Lend-Lease Act. The next day, the Lend-Lease Act began to be officially implemented, which lasted four and a half years. Previously, due to the serious isolationist sentiment in the United States, opposition to the United States' participation in the European war was at the peak. At the press conference, Roosevelt used the metaphor of a neighbor's house on fire, he had to borrow a water hose to put out the fire, and he could not charge for it first. He advocated using loans or leasing weapons to assist Britain, which was fighting against Nazi Germany. He said: "The United States must become the arsenal of democratic countries." The first to receive aid and receive the most aid was the United Kingdom. By the eve of Japan's surrender on August 31, 1945, the British Commonwealth received a total of 30 billion US dollars in loan aid, accounting for 60% of the total US loan expenditure. Among them, the United Kingdom received the most aid, which was 27 billion US dollars. US aid to the Soviet Union was implemented on October 1, 1941, after excluding the opposition of domestic isolationist forces. By September 20, 1945, the total value of goods actually delivered to the Soviet Union by the United States was $10.20 billion, plus other expenses, totaling $10.90 billion (the Soviet statistics were $9.80 billion). On May 6, 1941, Roosevelt officially announced that the Lend-Lease Act applied to China, and by September 3, 1945, the United States would give China $845 million in aid. London, 1942.
