nationalism is all well and kicking
Nationalism is fine (I'm very much in favor of some form of moderate nationalism as opposed to multi-culti ghettos).
Some type of nationalism is necessary for the functioning of the nation state (a flawed political system which nevertheless delivered the highest quality of life for the highest number in the history of the world).
Most political elites are in favor of discarding the nation-state model (while maintaining their positions within it - very hypocrytical) for something called the market state (think of all of Europe being London).
But a 19th century model of nationalism (geared to 19th century social and technological infrastructure) isn't going to work in the 21st. The trick is figuring out a viable model to preserve nation state services (education, law, infrastructure) which will be discarded in the coming market state.
