After Bismarck
Looking at the fact, that the period of time the first paragraph talks about is approximately 24 years long, longer than the time Bismarck was in charge, I doubt whether it is said enough about this period. My English is relatively bad, so I won’t do it myself. But here are some important issues:
The militarism the article talks about as implemented by the emperor was a social phenomenon, about which later (Weimar) politicians said, that it was one reason for WW I. Because of this all Germans were guilty for forcing the war and had to accept their responsibility. In the article it looks like the population didn’t support the militarism. It was just the other war around. Bismarck’s policy of a “satuierter Staat” (satisfied Country) was not  strongly supported by the Germans.
Also the sentence “Ein Platz an der Sonne” (a place at the Sun) should be mentioned. It stands for the German demand for colonies.

Also Wilhelm II’s fleet policy should be mentioned. The german fleet was heavily expanded, which made the British Empire look at Germany anxiously. “Politik der freien Hand”)

Also some of Wilhelm II’s unpredictable and foolish acts (for example during the second morocco-crisis (“Panthersprung nach Agadir”) or as he wrote the “Krüger Depesche” to congratulate Paul Kruger for fighting down a riot of British settlers, which was forced by the British government) should be placed here. 

Also a link to the Fashoda-crisis and its solution and the Entente Cordiale or the Triple Entente should be amended, as they were referred as a surrounding of Germany by enemies (“Umringt von Feinden”).

Another matter is, that it is not clear whether Bismarck himself would have been able to keep up his system of treaties for a longer period of time, because of it’s complexity. Some historians believe, that this system had to lead to a new European war, it only was the question, when.
I hope that an English-speaking person will read this and will take him- or herself some time to think of the things I tried to point out.
Indeed it is necessary, as the history part of the Germany article is let’s say … short. They are not even mentioning the Rhine confederation. Mit freundlichem Gruße
