Admiral Alfred von Tirpitz's design for Germany to achieve world power status through naval power, while at the same time addressing domestic issues, is referred to as the Tirpitz Plan. Politically, the Tirpitz Plan was marked by the Fleet Acts of 1898, 1900, 1908 and 1912. By 1914, they had given Germany the second-largest naval force in the world (roughly 40% smaller than the Royal Navy). It included seventeen modern dreadnoughts, five battlecruisers, twenty-five cruisers and twenty pre-dreadnought battleships as well as over forty submarines. Although including fairly unrealistic targets, the expansion programme was sufficient to alarm the British, starting a costly naval arms race and pushing the British into closer ties with the French. Tirpitz developed a "Risk Theory" whereby, if the German Imperial Navy reached a certain level of strength relative to the British Royal Navy, the British would try to avoid confrontation with Germany (that is, maintain a fleet in being). If the two navies fought, the German Navy would inflict enough damage on the British that the latter ran a risk of losing their naval dominance. Because the British relied on their navy to maintain control over the British Empire, Tirpitz felt they would opt to maintain naval supremacy in order to safeguard their empire, and let Germany become a world power, rather than lose the empire as the price of keeping Germany less powerful. This theory sparked a naval arms race between Germany and Great Britain in the first decade of the 20th century. This theory was based on the assumption that Great Britain would have to send its fleet into the German Bight for a close blockade of the ports (blockading Germany was the only way that the Royal Navy could seriously harm Germany), where the German Navy could force a battle. However, due to Germany's geographic location, Great Britain could employ a distant blockade by closing the entrance to the North Sea in the English Channel and the area between Bergen and the Shetland Islands. Faced with this option a German Admiral commented, "If the British do that, the role of our navy will be a sad one," correctly predicting the role the surface fleet would have during the First World War. Politically and strategically, Tirpitz's Risk Theory ensured its own failure. By its very nature it forced Britain into measures that would have been previously unacceptable to the British establishment. The necessity
