>the left:
nations are le heckin bad because of nazis or something so you shouldn't have a nation and everyone should be able to come here and take your stuff, no human being is illegal xD

>the Right:
nations have a duty to their citizens before anyone else: you should never prioritize foreigners over citizens
Life, Liberty and the Pursuit of happiness, etc etc
A nation is made up of its people, you can't change the people without changing the ideas of the nation
Replacing the people of a rich nation with the people of a poor nation will render the rich nation poor
