About the book: 2017 / This book is the most complete study to date of the relationship between two key personalities of the Second World War - I.V. Stalin and US President F.D. Roosevelt. It is about how strategic decisions on a global scale were made. About how two extraordinary people, overcoming prejudices, managed to change the course of all human history. Among the many discoveries of the author are previously unknown details of conversations between two world leaders “on the sidelines” of the Tehran and Yalta conferences. In these conversations and in personal correspondence, fragments of which are given by S. Butler, Stalin and Roosevelt discussed the post-war structure of the world, which was radically different from what we are used to now. It could well have become a reality if not for the untimely death of the American president. S. Butler also did not ignore the difficult relationship between the two leaders and the third member of the “Big Three” - British Prime Minister W. Churchill.
