Any chance you have a source for the bicycle tire story? I'm keen to read more about it (and similar stories).
I'm curious, did they stop teaching in school that Zersetzung happened in East Germany in the context of WWII? I was taught in High School about that.
While trying to find my source, I did find out Putin was in East Germany when the wall fell, and was working for KGB. Along with Stasi, Putin burned so much evidence of their wrongdoing, it broke the furnace.
So I guess Putin was a questionable fellow even back in the 1980's and 1990's!
