But rarely have two leaders worked together with such friendship and cooperation as American President Franklin Roosevelt and British Prime Minister Winston Churchill.

Yet,Churchill and Roosevelt disagreed about when  to attack Hitler in western Europe. And Churchill resisted Roosevelt's suggestions that Britain give up some of its colonies.
