The great Bismarck did not have a successor because his foreign policy was correct, but it went against the wishes of the general public, so many policies were abolished after he stepped down, probably for the following reasons.

First of all, Bismarck's foreign policy violated the likes and dislikes of the people. At ordinary times, Bismarck advocated making friends with Russia. At this time, the German military, political circles and public opinion circles hated Russia. Bismarck encouraged and supported France to expand its colonies in Africa, intensified internal friction, and used the contradiction between Britain and France to prevent its alliance. This policy has also been criticized by Germany.

Secondly, his foreign policy has dealt a great blow to people's vanity. Pismai disdained the idea of his great powers rising and navy expanding to build the world's first navy, because he saw the essence of these ideas, just to satisfy their vanity.

Bismarck could see through the essence of Charles Louis Napolé on Bonaparte's weakness at a glance, but he could not reasonably explain his diplomatic thoughts to later generations. As an orator, Bismarck's speech was lackluster, and his "iron speech" actually caused a huge political negative effect at that time, which was obviously his unspeakable performance.

Bismarck's diplomacy in his later period is one without merit. Bismarck saw an unprecedented risk and devoted himself to preventing it. In the eyes of others, he is like fighting an invisible enemy, which can only cause ridicule and cannot deepen respect.

Bismarck did not believe in the particularity of the German nation, but the German people were full of confidence in it. Bismarck did not believe that the German nation could take one as ten, but the German people believed that they could. In the end, history destroyed the rise of Germany and overthrew the inheritance of the giants.
