Even with
the murky waters of Cold War geopolitics which gave birth to and sustained the Wall in mind, and the tremendous social and economic dislocations that have accompanied the collapse of socialist economic systems and German reunification, we should still celebrate the fall of the Wall.
Because even though, in the poisonous atmosphere of Cold War mistrust, the Wall helped to avert a more serious confrontation between the USSR and the US, even though the US may have acquiesced in its construction and maintenance precisely for this reason, even though German reunification in the wake of its fall has been less than an unqualified blessing, it has always been fundamentally a stopgap measure born, at root, of misunderstanding, mistrust, miscommunication.
Miscommunication, misunderstanding and mistrust. Why should the East German regime have stopped free movement of people to, and from, the West, if it did not mistrust the West? If they did not want to restrict communication with the West? And such mistrust was born precisely out of miscommunication and misunderstanding between the superpowers, whose wariness of each other escalated out of all proportion into a worldwide shadow-play of power which left grotesque monuments the world over, of which the Wall was only one.
It was not only a monument to mistrust, but also a stopgap measure unsustainable in the long run. When there are such great economic and socio-political differentials as existed at the time between East and West Berlin, it is ultimately futile to try and stop the free movement of people in the direction of the differential. It's just like trying to stop a current flowing across a great potential difference, or, to take a slightly closer analogy, trying to prevent goods from moving to where prices for them are very much higher. It could be done, but you'd have to expend a lot of effort and resources in the process. So much effort, sometimes, it wouldn't make sense to try.
So even if the common portrayal of the fall of the Wall as being symbolic of the triumph of democracy and freedom over tyranny is romanticised and oversimplified, still we should see the event as a vindication of common sense and of free movement and open communication. Still something worth celebrating.
