The absence of war in Europe was not a limitation but a good thing after the long Napoleon wars. Germany was quite weak so Bismarck helped Germany to gain strength in this way. But his system was not stable and a web of complex relations among the other nations; so, it was not possible to maintain the same system after Bismarck. Besides, Bismarck's system led France and Russia into an imperialistic competition, which would create a conflict among the other states. Therefore, III and IV were the limitations of the Bismarckian system.
