Funny how bad turning points make us forget good ones. German Media almost exclusively used Schicksalstag 9/11 as their day of fate in 1989. I was amazed that googling "Schicksalstag" under google images got zero images of the wall falling down, but plenty of the twin towers falling down.
I read through many articles commemorating the twentieth anniversary, but very little mention of the 9/11 duality of the date nor a comparison of the two events as global turning points.
This day of joy and relief should be remembered and commemorated. After all, the date is so easy to remember!
