EU politicians are just too dependent on keeping the status quo of the last decade. The status quo is how they got to their position so they have no incentive to change anything (Starmer, Merz, Marcon, Von der Lyen. Yuck). By the time they finally get the shove they need to rapidly decouple, e.g. when America invades The Hague* to rescue Netanyahu from war crimes charges, it will be when they're already on the edge of the proverbial cliff.
