When I was a kid, from 1981-1983, I lived in Bad Vilbel, close to Frankfurt a.M.
My Dad was in the U.S. Army, and our housing complex (our house was on Beethoven Strasse) was encircled in barbed wire, patrolled by military police (MP's) with German Shepherds, and there was a check point at the front of the housing area where MPs would check your military ID, then put a mirror under your car before you drove into the neighborhood.
We (the kids of U.S. military personnel) were taken to school on a DIFFERENT touring style (commercial tourist) bus everyday. Our school (Atterberry Elementary) received bomb threats regularly, every few months, and we had to be evacuated. I was in 2nd and 3rd grade at that time.
Vehicles of U.S. soldiers had been rigged with bombs that detonated when the vehicle was started, so a few soldiers lost thier lives as they started their cars to go to work in the morning.
Why was all this going on?
Baader Meinhof.
They are one of the few terrorist organizations worldwide that deemed it acceptable to target children of U.S. government staff for assassination in order to make a statement.
Crazy, extremist, militant Germans that had a really big problem with the U.S.A.
Interesting you should mention them, I haven't heard that name for quite some time.
