This book, first published in 1944, assesses the prospects of peace following the Allied victory in the Second World War. It examines the tasks that victory would impose on the victors; the development during the war of US policies, military and political; the errors that caused the war; and the viewpoints and needs of the Allied powers. Concluding that the future peace could be only achieved through the power and influence of the United States, it argues that the process of uniting the Allies in peace would need greater statesmanship than united them in war against a common enemy.
