It depends. Outrage against the US had already peaked when Merkel was spied on. Currently it looks as if the evidence has to be verified before doing anything about it, and there is an aspect of confusion about what to do with an ally that is still extremely valuable. One aspect is that the US has been doing stuff that is incompatible both with their and our constitution. Moreover, Germany is constitutionally prohibited from participating in any war on the attacker's side. Hosting drone operators would violate this commandment.
