Before WW1, Germany build up a navy on the assumption that the Royal Navy would be deterred from attacking a smaller force for fear of being weakened against other navies despite its history of charging headlong into much larger fleets. What if instead, the Kaiser had invested in commerce raiders? This way, he can harass trade, instead of having a big fleet blockaded from the rest of the world, only able to fight 1 inconclusive battle the whole war. Will it change anything?
