I'd be really curious how it'd be possible. Are the immigrants here in their original nation or this one? What about nations in civil war that aren't one nation? And on and on... My guess is that this language is somehow not capturing the original meaning. Or it was responsive to a particular time when nations were more clear-cut. At any rate, it makes no sense. "Our" nation encompasses everyone from Charles Manson to MLK. So are we judged as a group for our MLKs or for our Mansons?
