Do you consider nationalism a positive ideology?

Not at all. Nationalism will be to the 21st century what fascism was to the 20th.

Nationalism serves to create even more defined in-group/out-group dynamics than what currently exist. This is fundamentally divisive of populations, and with scarce natural resources, arable land, etc, this leads, and will continue to lead, to significant armed conflict.

This can be avoided if one's "nation" defines itself in an inclusive manner, as opposed to an exclusive one. However, this is *rare*, if not nonexistent.

In a quickly globalizing world, with rising multiculturalism and a great need for solidarity among people with divergent origins, nationalism seems to be more of an impediment. Future humans may look back and see nationalism as being a divisive force, rather than a source of pride. Why? Social capital needs to be generated on a global scale to bring about real change in the power structures that control this planet. Social capital that is based on nationality does not serve this end nearly as well.

Without colonialism, patriotic feelings aroused by one's culture, heritage and nation are perfectly legitimate. Traditionally, the fervor of anti-colonialism induced the pain of self-sacrifice, a divine rite of passage into nationhood. We must respect the fervor of nationalism in third-world and second-world countries. A reckless superpower, can, through the influence of a maniacal, evil and depraved inner circle, confuse us by mixing pure and good anti-colonial nationalism based in self-defense, with the preemptive evils of imperial colonialism. Modern examples include China and Tibet, Sadam and Kuwait, and the Imperialist Putin exerting his influence over the Syrians. Our divine obligation is to support third-world and second-world countries and immigrants if they wish to display their patriotism.

Its all about what the intentions are of the nation. During WW2 Russia was able to keep a strong fighting force with positive nationalism. At the same time the U.S. was able to produce large amounts of money and resources through nationalism. Its all about who is in power. North Korea is showing us what bad nationalism can do.

It's useful but dangerous, like war. I wouldn't say it's a good thing, but it's sometimes better than the alternative.

Political nationalism has mostly been very destructive, but the Space Race in the 50s and 60s is one example of a positive contribution of nationalism I suppose.
