CAN THE ORIGINS OF WORLD WAR ONE BE FOUND HERE?

Can the origins of WW1 be found here?

The Papers of Viscount Esher (Reginald Brett)

"One Wintry Afternoon in February 1891, three men were engaged in earnest conversation in London. From that conversation were to flow consequences of the greatest importance to the British Empire and to the world as a whole. For these men were organizing a secret society that was, for more than fifty years, to be one of the most important forces in the formulation and execution of British imperial and foreign policy.

The three men who were thus engaged were already well known in England. The leader was Cecil Rhodes, fabulously wealthy empire builder and the most important person in South Africa. The second was William T. Stead, the famous, and probably also the most sensational, journalist of the day. The third was Reginald Baliol Brett, later known as Lord Esher, friend and confidant of Queen Victoria, and later to be the most influential advisor of King Edward VII and King George V.

So Esher was the link between the Monarchy and everything else in the power structure, and met the king daily for discussion, and according to Quigley he was "the most influential advisor of King Edward VII and King George V." Edward VII had Esher reform the British Army (in preparation for WW1?).

We know that:
1. as Grand Master of the United Grand Lodge of England, Prince Edward began to diplomatically isolate Germany;
2. King George V told Germany that Great Britain would not join any war while telling Sir Edward Grey to get Great Britain into any war that occured.

So if Esher was their most influential advisor, I'm wondering if Esher is the mastermind or just the fixer, the "Yes" man.
