AHC: How long can the Wall stand?

With a POD in 1985 at the earliest, how long do you believe that the Wall can stand?
How does this maximum decrease (or increase) with POD in 1986, 87, 88 and 89?


I think that the Wall could still be standing in 1995 or even 2000, but please comment! Try to develop a TL!
 
Yes, and to the German-German wall.

Can Erich's prophecy, given in early 1989, be fulfilled which was that "the Wall will still stand in 50, even in 100 years"?
When will the Soviet Union collapse, how, and how will the world fare? What about the rest of Eastern Europe?

I was brought to such a challenge by watching a film "60 Jahre Deutschland" where this prophecy was quoted in a televised speech by Erich Honecker, and where they said that even in 1988, the German Divide and Iron Curtain were thought to be (more or less) permanent. So: Contribute!

Close this Gate, Let this Wall stand, Mr. Honecker!
