'Scholar'
Such interpretation is nicely confirmed by the fact that 1914 ended the Gentile Times with the Kingdom established in heaven as evidenced by the ourbreak of the Great War in 1914.
The outbreak of World War I in June of 1914 does not in any way provide any proof whatsoever for a prophecy of the Bible Students to be fulfilled "with suddenness and force not long after October, 1914" (The Watchtower, 15 May 1911). Additionally you have not provided any justification for applying the Gentile Times to a period beginning prior to 70AD as required by the original language in the book of Luke.
Historians are aware of the fact that there were many 'great wars' or conflicts in modern history but the significance of 1914 as the truly Great War or First World War is not seriously challenged by competent historians, statesmen and intellectuals.
Your use of the word 'competent' is an 'emporor's new clothes' gimmick, to make it seem that anyone who disagrees with your position is therefore 'incompetent'. It is akin to expressions such as "all intelligent people realise", "thinking people agree" etc.
The mere appearance of your little book simply reflects a novel opinion but remember that terms of 'Great War' and 'First World War' were not coined by us but by wordly historians so if you have a beef about this matter then take the matter up with wordly historians.
They are still simply labels, and do not at all reflect the early Bible Students' prophecies of what would supposedly occur. Indeed not all nations of the world were involved in World War I.
