According to Wilhelm II, what "means" and characteristics were most important for the German Empire to succeed? How do Wilhelm II's claims relate to the argument made by Froude?

The correct answer to this open question is the following.

Although there are no options or further references attached we can say the following.

According to Wilhelm II, the "means" and characteristics that were most important for the German Empire to succeed were that the different states had the goodwill to work together and trust each other to get a much-needed agreement, leaving behind personal political agendas and interests, in order to create the German Confederation of the 39 states on order to strengthen their economies in a time when there were many rivalries and enemies in Europe,

This German Confederation was the result of the negotiations during the Congress of Viena of 1815.

Unfortunately, as it was a time of so much rivalry, the German Confederation only lasted until 1848 due to the many political and economic differences between Prussia and Austria. Some years of turmoil would follow after this break until diplomats could improve things in 1866 with the creation of the North German Confederation.
