Ideally, the border of a nation state extends far enough to include all the members of the nation, and all of the national homeland. Again, in practice, some of them always live on the 'wrong side' of the border. Part of the national homeland may be there too, and it may be governed by the 'wrong' nation. The response to the non-inclusion of territory and population may take the form of irredentism: demands to annex "unredeemed" territory and incorporate it into the nation state.
