Bismarck the statesman was one for the ages. He craftily upended his legions of opponents, both outside and inside the German principalities, and instigated three swift, decisive, yet limited wars to crush Denmark, then Austria, then France, but he kept the state of Austria-Hungary on the Danube for the sake of the balance of power. He created pretexts to attack when in a commanding position or baited the other countries into launching the wars after he had isolated them diplomatically.
