The EU will do nothing if it falls outside of the US imperial mantle because it’s not a proper political entity, it never was, it never will. Maybe individual countries like Poland will try to do something, but they’re too small in the great scheme of things.
If Germany had any strategic autonomy left (which they don’t, they’re just a US vassal through and through) they would do a second Rapallo, maybe this time also involving China, at that point they’d still have a chance to put their economy back on track.
