I think that Germany relies far more on the EU to maintain national stability, they are dyed in the wool Europeans. Angie recently made a statement to the effect that Germanys place is in a stable EU. The Bundeswehr is dramatically underfunded and has been for years. They were still operating F4s long after ours and the USAFs had been turned into coke cans (Oct 1992 last RAF F4. Last Luftwaffe F4 2012 or thereabouts). As there are a few problems with the A400 they're still using C160s, which were conceived for European operations, not world wide ops. The Luftwaffe helos are also knackered. Then there's the Army and the Navy with their own problems. On top of which in a volunteer force they are having recruiting problems, the armed forces just aren't regarded as attractive.The core nations, Germany, Benelux, UK, Italy and Spain have a vested interest in maintaining the alliance as it forms part of their national stability and gives them close bonds to the US. France only restored its full status about 6 years ago and they're doing quite well out of the deal.
The term the Germans use for their forces is "kaputt gespart", death of a thousand savings cuts. The Defence Minister, von der Layen claims that spending will be increased, but there will of course be a considerable flash to bang delay.
