November 9 should be the day when Germans have one big party. It’s a day that should be akin to the July 4 in the USA or July 14 in France. A day when Germans look back and remember something positive, something constructive about which they can be justifiably proud.
November 9 1989 was the day that the “anti-fascist protection wall” – or the Berlin Wall to you and me – was finally and definitively breached. Berlin would no longer be divided by barbed wire and land mines. Overnight, German, European and indeed global geopolitics fundamentally changed.
