Does this decision/ruling mean that an American soldier can not safely cross German soil due to universal jurisdiction? Practically speaking given the international political dynamics I don't suppose they will realistically ever be so prosecuted or otherwise made so unwelcome but is there anything legally preventing it from happening?
How unfathomable would it be for a radical/renegade anti imperialist law student to rise through the ranks of the German prosecutorial or judiciary services and make a big wave by prosecuting American troops for their army's criminal adventures around the world along the lines of Baltasar Garzon in Spain?
Update - This was the answer by user PMF that inspired my question:
"The court however ruled that being part of a "mass murder machine" is enough to be held responsible."
