"All treaties between nations are valid only with the reservation clause: rebus sic stantibus. They do not pledge a State for ever."

“Martial force is the basis of all political virtues; in the rich treasure of Germany's glories the Prussian military glory is a jewel as precious, as loyally acquired as the masterpieces of our poets and our thinkers; the sacred character of the allegiance to the flag is a witness to the moral force of our people. Therefore let our Liberalism return to those ancient German convictions.”

“...One thing alone can drive us, against our will, beyond these modest desires. If the next French attack against the German Empire found the Dutch among the enemy faction, at that exact moment Holland, by her senseless mistrust, would herself be precipitated into her ruin. Then, and only then, would it be necessary to attempt to put an end once and for all to the millenary struggle over the ruins of ancient Lotharingia, and once more to compel the countries of the Lower Rhine perforce to rejoin the great people whom they abandoned long ago. Holland holds in her hands the means of averting, by a just and fearless policy, these interminable conflagrations. The majestic progress of German affairs, the unity of our Empire from the North Sea to Lake Constance, the complete organisation of this unity are not to be impeded by the outcries of small peoples who cannot forget the splendour of past days.”

“The enlargement of Prussian power is little by little becoming a demand of justice.”

“A thousand touching traits testify to the sacred power of the love which a righteous war awakes in noble nations.”

“God will see to it that war always recurs as a drastic medicine for the human race.”

“Those who preach the nonsense of eternal peace do not understand Aryan national life.”
