The Background Berlin, after WW2 proved the nightmare nobody could wake up from. The cold war begins and is set in place with a wall dividing Berlin. The wall becomes a symbol, differing in meaning to both sides.
Nobody does, it never becomes the wonder-wall.
Years of suffering later, the wall is torn down, as capitalism celebrates it's victory of the cold war. There are no street parties in Britain, not that I can remember anyway, but the Berlinners look excited. Freedom, as the West likes to practise it. Strange times in hindsight. Particularly strange to experience in the very recent aftermath.
