Covid, Russia and the axis of US+Israel has done massive damage to the European psyche.
Covid showed us how economically dependent we are to major manufacturing countries like China. Paper money != ability to manufacture.
Russia broke any notion of peace that can be funded by cheap energy. It will always be a tool used against you, and Russia will not change.
The axis of US+Israel is breaking down the international system of laws and diplomacy. It’s going to be in a state even worse than the heights of the Cold War. Nukes are now a more favored instrument of peace compared to diplomacy.
Is it worth fighting for what we had, or should we fight for something better? Who knows.
(Edit: I don’t think non-Europeans can appreciate the whiplash suffered in our populations. In the span of around two years, European leaders drew red lines on political, economical and cultural decoupling from Russia based on human rights and the rule of law, then had to explain why preventable atrocities happening to civilians in the Mideast is not against our values and laws concerning human rights.)
