the banks to whom money is owed just happen to be German
Care to check your facts? Outstanding bonds are held first and foremost by french banks (around 25%) then by BENELUX banks (around 13,5%) and then by german ones (around 7%). Asia and Africa hold round 19% while the rest of the EU holds around the same as BENELUX. In new bonds this year germany and austria combined only bought around 4,8%, behind spain with 34%, UK with 20,3%, Asia with 13,3%, Nordic countries with 6,2% and France and BENELUX each with 5%.
By the way, that information is from Dirección General del Tesoro y Política Financiera, not some foreign conspiracy theorist.
The answer being to provide a training ground for somebody's Condor Legions perhaps?
Not germans anymore, they are in the process of pretty much dismantling their whole military as they have no real need of it, anybody wishing a go at them needs to wade through the whole EU first anyway.
