We are too afraid of change and having to take responsibilities. Delegating to the US worked for decades, and it’s very hard to accept that we’ve done a mistake and need to take some risks ourselves. I feel it’s the same issue we have at European countries level.
But also, the EU is still a patchwork of entities that do not have a common vision of what the future should be. Hopefully losing our largest ally will push towards a closer, more federalist union. There is still so much work to do to unify the single market. I’m watching closely what is going on with the 28th regime[0] for that purpose
