I have one first question. Do you say that the coming election is a turning point irrespective of the result, or because you expect the right (CDU/CSU/FDP) to win, with a strong showing of the Left party, and thus the SPD to desintegrate? Or conversely, you expect no one to have a majority, and thus the CDU and SPD to from a grand coalition that fill kill them both once and for all (you seem to say that the CDU had run its course in the late 80s).
But what's next? In the long run, we're all dead. John Maynard Keynes
As to what's next, who knows?
