"Violence is the last refuge of the incompetent."

I think the EU is "beyond" war - at the moment.
Europe has never been in such a good state. It's not just that we're more advanced and prosperous than we used to, IMO. Other united entities may still be barbarian misantropes...

There is no way a civilised humanist can use war to resolve a conflict of interest. (applies to religious humanists as well as secular)
Self defense may be possible.

How deep and resistant to corrosives is the lacquer of civilisation, though?
I'm certain I'm civilised to the bone myself, but examples of how surprisingly, shockingly easy it peels off abound.

I hope the UN will be revitalised, and become what it's intended to be instead of a stomping ground for those who have concern only for power and wealth.
