Nationalism connotes identification with and loyalty to one s nation as just defined.
It does not refer to loyalty to one s country. If the world is one great commons, in which all food is shared equally, then we are lost. Those who breed faster will replace the rest. In a less than perfect world, the allocation of rights based on territory must be defended if a ruinous breeding race is to be avoided. Fortunate minorities must act as the trustees of a civilization that is threatened by uninformed good intentions.
