You mean the biggest American base in Europe? It's true, Germany can't make an army, but they're expected to be the stand ins for the real one.

I'm guessing that's the reason for the leak. Someone in the Bundeswehr is hoping it'll finally force their politicians to give them funding due to public pressure - because despite all the talk at the start of the Ukraine war about how Germany will build a massive army and comission an aircraft carrier, it's been nearly 2 years and they haven't done shit.
