The United States is a "civic" nation and not an "ethnic" nation. American citizenship is not based on belonging to a particular ethnicity, but on political loyalty to American democracy and values. Regimes based on ethnicity, which support the doctrine of perpetual allegiance as one is always a member of the ethnic nation, are not concerned with assimilating non-ethnics since they can never become true citizens. In contrast, the essence of a civic nation makes it imperative that immigrants assimilate into the greater whole as there is not an "ethnic" cohesiveness uniting the populace
