Paired with Blair

International | In the new war on terrorism, President Bush and British Prime Minister Tony Blair reprise old roles | Mindy Belz

When Great Britain's last great wartime alliance with the United States began, Winston Churchill told Congress in 1941 that the forces "ranged against us are enormous. They are bitter, they are ruthless ... they will stop at nothing." Common cause knit the prime minister to U.S. President Franklin D. Roosevelt during Germany's battle of terror over Britain, and has linked the transatlantic forces once again.

Conversation between Churchill and FDR at first required clunky telephones until engineers developed "Sigsaly," the latest in telecommunications to allow frequent encrypted contact between the two heads of state. FDR worked the phones from the Oval Office; Mr. Churchill, from a converted broom closet in fortified war rooms underground.
