It is not a so-called "regionalism."

Regards,
Sorry, Germany is unwilling to spend the money required to have a powerful military. The people are unwilling to join the military in significant numbers. The leaders are unwilling to utilize the military even if they had one. Finally, France, England, Austria, Italy, Greece, Poland, etc.. do not trust Germany.
Not going to happen.
