It is much more important for us to want that which is right than it is simply to know what is right. This is particularly true in politics. Many know why Germany has collapsed, but few have the will to end its misfortunes. But in politics is is also important not only what one wants, but what one accomplishes. Progress requires accomplishment.
Leadership means to want something, and to be able to show the way to realize what one wants.
History judges by what has been done. We Germans need to realize that. Politics is a public affair, and one cannot apply the laws of private matters to public matters. We Germans often tend to confuse the the desire for something with the ability to do it, and to forgive the incompetent who says that he wanted good and proper things. That is irrelevant, just as we do not care if someone wants to play the violin.
