I feel like a lot of our (EU) legal structures are totally inadequate for long term periods of peace. Eventually everything gets bloated and ossified and vested interests gain more and more influence/control.

Existential threats always seem to have an interesting way of unlocking progress.

Just look at how quickly Germany was able to build the north sea LNG terminals in the face of the russian gas crisis [1].
