How can NATO owe Germany when Germany's a member state of NATO? That's like saying you're in debt to yourself because you bought things from the grocery store.
....2017... having to beg Germany to spend 1%of their budget on their own military because they are going on an international charity rampage...
basically they are going above and beyond on peacekeeping, foreign aid and training missions, on that they should be applauded, but at the same time they are not adequately equipping and maintaining their own military equipment to mandatory NATO obligation standards which sets a bad precedent if they ever want other countries to share a equal and proportionate burden of the alliance in the future...
