Actually the Germans are (finally) ramping up their military ,albeit at a relaxed pace.
1.They are building a new class of airdefence frigates,which offers pretty much most of the capabilities of 'Aegis' equipped ships(barring land attack).
2.They are building a new class of Diesel electric subs which use air independent propulsion for far greater endurance .
3.Their Eurofighters will reach optimum operational capability when it recieves the Meteor BVRAAM & the 'Taurus' Stand off cruise missile & are trying to export the aircraft along with the Brits to Australia,Singapore,India(which has a requirement for over 120 jets).
4.They are building up rapid reaction brigades in the German army for quicker reaction to 'Global trouble spots'.
5. For the nuclear part,there is always the French(!!!!) ,besides most of Germany's recent moves are aimed at building a pan European defence initiative.
You are well informed; one thing: we do NOT rely on the French on nuclear weapons. For us, the United States are our most important partner for the defense with nuclear weapons. I know that there are still nukes on German soil, and even a high-ranking military official has confirmed that we continue to cooperate with the US on that.
