What's exactly the failure of EU that I'm talking about. There's little cooperation at EU level. Only some members cooperate on ad-hoc basis. But in general everybody is out for themselves.

More examples - Poland closing borders and not allowing people to pass it to return to their home countries. Or little centralised plan to close borders, both internal and external. Or countries essentially nationalising airlines en-masse, which was strictly forbidden by EU rules. Or Belgium citizens going to party to Netherlands since one has shut down everything and the other one is banking on herd immunity.
