Nationalism, in contrast to national identity, is a political programm
e that always has exclusionary effects. It supposes that groups define
d as 'nations' can and should form territorial states of the kind that
came into being from the time of the American and French Revolutions.
In practice, the nationalist programme aims at constructing sovereign
state control over a clearly demarcated territory. Since nations rare
ly live physically apart from other nations, nationalism implies separ
atism and xenophobia. Nationalists are not merely opposed to 'foreigne
rs'. They are also in favour of setting up 'their' own state, in which
'their' nation holds a monopoly of power, or at least enjoys a privil
eged official status. Not surprisingly, cultural discrimination and ph
ysical harassment and, in extreme cases, mass expulsion and genocide o
ften follow.
