I find it funny that everyone complains that Europeans currently just talk and never act.. Every time Europeans acted, it ended in either a world war, of half of the war colonized.. So not sure if you really want Europeans to act..
This is also why anarchies are not very stable.
The international order, with each nation being kinda like an individual person, has few enough actors that the distinctions between "anarchy", "democracy", and "dictatorship" are blurry.
