to concentrate the fleet against the German threat involved Britain making arrangements with other powers that enabled her to return the bulk of her naval forces to Home Waters. The first evidence of this is seen in the Anglo-Japanese treaty of 1902 that enabled the battleships of the China squadron to be re-allocated back to Europe. The Japanese fleet, largely constructed in British shipyards, then proceeded to utterly destroy the Russian navy in the war of 1904–06, removing Russia as a credible maritime opponent. The necessity to reduce the Mediterranean Fleet in order to reinforce the navy in home waters was also a powerful influence in its détente and Entente Cordiale with the French. By forcing the British to come to terms with its most traditional opponent, Tirpitz scuttled his own policy. Britain was no longer at 'risk' from France, and the Japanese destruction of the Russian fleet removed that nation as a naval threat. In the space of a few years, Germany was faced with virtually the whole strength of the Royal Navy deployed against its own fleet, and Britain committed to her list of potential enemies. The Tirpitz 'risk theory' made it more probable that, in any future conflict between the European powers, Britain would be on the side of Germany's foes, and that the full force of the most powerful navy in the world would be concentrated against her fleet.
