In the 1930s, Adolph Hitler had powerful friends in England who agreed with his anti-Semitic and racist policies. On country weekends, some of the most prominent members of English society and even the American Ambassador to the Court of St. James gathered at Cliveden Manor. There on the estate of Lord and Lady Astor, they plotted ways of keeping Great Britain out of the war with Nazi Germany. The Cliveden Set, as they were called, put enormous pressure on British Prime Minister Neville Chamberlain to appease Herr Hitler. As history records, Chamberlain's appeasement of Hitler and the sell-out of the countries overrun by the Nazi war machine led to World War II. As a result, millions of innocent people lost their lives and the Jews of Europe were almost exterminated. Some of the sons and daughters of the men and women lost to the Nazi menace in World War II swore to take revenge on the surviving members of the Cliveden Set. For that purpose, they formed a society so secret its name is still unknown. "JFK: The Umbrella Conspiracy" details how the work of assassins in Dealey Plaza on November 22, 1963 was actually designed to kill more than one Kennedy--and did.
