WHY DID GREAT BRITAIN NOT DECLARE ITSELF ON THE SIDE OF FRANCE AND RUSSIA?

These are the words spoken to Russian Foreign Minister Sazonov to British Ambassador to Russia Sir George Buchanan:

Austria would not have acted so aggressively without the consent of Germany. I hope the British government will declare itself on the side of France and Russia without delay.

This is of course referring to the Triple Entente proposed by Grand Master of the United Grand Lodge of England King Edward VII and finalised by Sir Edward Grey.

Instead King George V told Germany that Great Britain hoped to stay out of the war while demanding that Sir Edward Grey get Great Britain into any war, leading to Grey doing a U-turn over Belgium, having shown little or no concern over Belgium until Germany invaded.

We have to look at the power of Great Britain at the time. It was the largest empire/empah on the planet at the time, though economically less powerful than Germany and the USA, which was the reason why Great Britain engineered the war in a bid to create a world government that it would control.

What if the most powerful empah on the planet had immediately declared itself on the side of France and Russia, as requested above?

Would Germany have backed down?

Russia mobilised on 31st July.

Germany declared war on Russia the next day.

Why did Russia mobilise? Because Austro-Hungary declared war on Serbia on 28th July.

And Germany had indeed given "blank cheque" support to Austro-Hungary.

So why did Great Britain not declare itself, as the Triple Entente proposed, on the side of France and Russia and thus deter Germany from supporting Austro-Hungary who would then not have declared war on Serbia on 28th July thus provoking Russian mobilisation?
