its own internal affairs and economic recovery, espousing an isolationist policy. When the US raised tariffs in 1930, the British retaliated by raising their tariffs against outside countries (such as the US) while giving special trade preferences inside the Commonwealth. The US demanded these special trade preferences be ended in 1946 in exchange for a large loan. From 1929 to 1932, the overall world total of all trade plunged by over two-thirds, while trade between the US and Britain shrank from $848 million to $288 million, a decline of two-thirds (66%). Proponents of the high 1930 tariff it never expected this, and support for high tariffs rapidly eroded. When Britain in 1933 called a worldwide London Economic Conference to help resolve the depression, President Franklin D. Roosevelt stunned the world by suddenly refusing to cooperate, ending Conference usefulness overnight. Tensions over the Irish question faded with the independence of the Irish Free State in 1922. The American Irish had achieved their goal, and in 1938 their most outstanding spokesmen Joseph P. Kennedy, a Democrat close to Roosevelt, became ambassador to the Court of St. James's. He moved in high London society and his daughter married into the aristocracy. Kennedy supported the Neville Chamberlain policy of appeasement toward Germany, and when the war began he advised Washington that prospects for Britain's survival were bleak. When Winston Churchill came to power in 1940, Kennedy lost all his influence in London and Washington. Washington analysts paid more attention to the measured optimism of Lieutenant Colonel Bradford G. Chynoweth, the War Department's military attache in London. World War II Although many of the American people were sympathetic to Britain during the war with Nazi Germany, there was widespread opposition to American intervention in European affairs. This was reflected in a series of Neutrality Acts ratified by the United States Congress in 1935, 1936, and 1937. However, President Roosevelt's policy of cash-and-carry still allowed Britain and France to order munitions from the United States and carry them home. As ambassador to the United States in 1939–40, Lord Lothian supported Lend-Lease and urged Prime Minister Winston Churchill to work more closely with President Franklin Roosevelt. His success can be attributed to his understanding of American politics and culture, his skills in traditional diplomacy, his role as intermediary between Churchill and Roosevelt, and the efficiency of Britain's wartime propaganda agencies.
