Is this the failure of federalism? and therefor the success of centralize nation?
or is this the failure of federalism country who have many different cultures? (Canada, but also Belgium(Waloons, Flanders), and to another extent Iraq(Kurds, Chiites, Sunnites...))

What do you think? I always saw federalism as a good soltution to decentralize states, but now... I am not really sure ??
