Yeah, one would think post-Brexit and post-pandemic and post-Russian invasion of Ukraine people would in general be more aware of interdependence in trade, finance, manufacturing, etc. but apparently not. (Yes, they did say that before WWI, and today it's a million times more intertwined)
It still matters game theoretically who loses more on not having a trade, and US having the reserve currency means that it has clearly more power over EU than the other way around.
