But everyone including the US acknowledges that they don’t need the ridiculous number of nuclear weapons any longer. Especially given that as Trump said Europe is responsible for itself now.
You should peruse the obligations the USA signed up to in Article VI of the NNTP.
The ICJ (the UN one the US congress ratfied) ruled waaay back in 1996 that article VI of the NNPT implies "There exists an obligation to pursue in good faith and bring to a conclusion negotiations leading to nuclear disarmament in all its aspects under strict and effective international control."
So, every European country should acquire nuclear weapons and develop MIRVs that can overwhelm Trump’s Golden Shower so they can dissuade the US from invading.
If Europe didn't already have top secret "Break in case the US goes rogue" plans then they were being negligent and I can assure you they are making those plans now.
I’m sure the plans are there. I’m unsure if they were adequately funded.
You see, for instance, a lot of high tech weapons come from the US and, presumably, have all sorts of kill switches. We, at least, need to stop buying those.
