This is a controversial book from the 1950s that described Germany's war aims in World War 1 as expansive and imperialist in nature. The stress is on territorial aims, which included relations with the ports of the Low countries in the West, expansion into territories that were until recently under Soviet influence in the East and the idea of Mittelafrika (middle Africa) under which German colonies in East and West Africa (Tanzania, Cameroon, Namibia) would be united by takeover of the Belgian Congo and neighboring countries. The result is to present Germany's foreign policy as outside international norms in its expansionism.
This gave rise to a controversy that should probably be studied by anyone wanting a balanced view of the subject. It was the spirit of the times that the book itself made it into English and its views were widely accepted, prior to scholarly attention moving to World War 2. German domestic politics are also not addressed in the book save as they impinge on foreign policy. It gives an insight into German war aims, but possibly confuses speculative plans when victory was hoped for with actual negotiations. On the whole I found it readable and absorbing. The very scope of the thinking sometimes seems to belong to a bygone age of European ambitions.
