B) a quick end to the war, world war one submarine warfare was unristrected, which was a major cause why american entered the war, germany resited to submarine warfare, why did the resort to submarine warfare, that may have provoked america? By 1917, the war was not going well for Germany on the Western Front. Unrestricted submarine warfare was a result of desperation and the belief that the ferocity of such a tactic might just keep America out of the war if the results were spectacular and shocking enough. he Battle of Jutland showed that the German Navy was not strong enough to defeat the Royal Navy. Therefore any attempt by the German surface fleet to attack British merchant ships was not tenable as any fleet leaving bases like Kiel would have been met with a considerable fleet from the Royal Navy. Therefore, any attacks on Britain’s lifeline of shipping from America would have to be done by submarines. Rather than do this piecemeal, Bethmann Hollweg decided on a policy of wholesale unrestricted attack.
