Forming new alliances like AUKUS or the QUAD does not mean creating new blocs. “Inter-epoch” alliances, for the time in which we find ourselves, will be less formalised and more loosely structured. “Old” blocs such as NATO or the European Union noticeably lose their maneuverability. They are slow to react and difficult to reform. New alliances, on the other hand, may be less durable despite their flexibility and suddenly end their lives. We must therefore be ready for many sudden twists and turns in world politics.
