I guess Erich Honecker, when he pronounced these words on January 19, 1989 was either bluffing or hadn't reckoned with the "many small people who in many small places [did] many small things [and altered] the face of the world" (for source, see here).
Or, to be totally cynical, the surge of people across the Wall in those heady days may not so much have been down to fear of the Stasi or politcal idealism, but more to do with the pulling power of Coca Cola and electronic goods.
On November 9 1989, I was sleeping fairly rough on the floor of a Bangkok guesthouse. This was not my first taste of Asia (I had already the previous year been in Hong Kong and Macao researching a book), but the months that followed took me on a great adventure inspired in part by the more idealistic elements of what was happening back in the heart of Europe.
And I returned home in time to see the German reunification celebrations. A different person. A different Europe. A different world.
So where were you when the Berlin Wall fell?
