It will be hard for Germany to find a sensible role in the post Trump NATO.
UK and France have their nuclear deterrents and continuing global commitments. The Baltic and Mediterranean members have clear challenges in their regions.
No longer a frontline state and with an understandable aversion to deploying military force outside its own borders Germany cannot recreate its impressive frontline force of the late 1980s.
In some ways like the US and UK in the past Germany needs to use its continuing economic and industrial muscle to help its neighbours in Poland and elsewhere re-arm.
