What argument is otto von Bismarck making in the wars of German unification?

Otto Von Bismarck argued for the unification of Germany through a series of strategic wars that would strengthen Prussian influence and consolidate the German states under Prussian leadership. He believed that military conflict, rather than diplomacy, was necessary to achieve unification, as demonstrated in the wars against Denmark, Austria, and France. Bismarck utilized nationalism and the idea of a common German identity to rally support, ultimately leading to the establishment of the German Empire in 1871. His approach emphasized realpolitik, prioritizing practical outcomes over ideological considerations.
