The book Imagined Communities (Benedict Anderson) touches on this, making the case that in modern times, "nation" has replaced the cultural narrative purpose previously held by "tribe," "village," "royal subject," or "religion."

The shared thread among these is (in ever widening circles) a story people tell themselves to justify precisely why, for example, the actions of someone you'll never meet in Tulsa, OK have any bearing whatsoever on the fate of you, a person in Lincoln, NE.

One can see how this leaves an individual in a tenuous place if one doesn't feel particularly connected to nationhood (one can also see how being too connected to nationhood, in an exclusionary way, can also have deleterious consequences, and how not unlike differing forms of Christianity, differing concepts on what the 'soul' of a nation is can foment internal strife).

(To be clear: those fates are intertwined to some extent; the world we live in grows ever smaller due to the power of up-scaled influence of action granted by technology. But "nation" is a sort of fiction we tell ourselves to fit all that complexity into the slippery meat between human ears).
