Agreed.
Baltic states are doing exactly what is described by definition of the term nationalism above. At the moment they are exactly national countries, defending their national self-determination. Sometimes it turns ugly, but that's how they want to protect their national identity, after many years of different kind of occupation.
This statement is false, at least if you apply it to Russians. I am a ethnic Russian myself (Russian Canadian), and may I say, I Know the Russian history.
All the time in Russian history the Empire (under different names) fought against the Russian nationalism.
Unfortunately to Russians, most of the times in the last five centuries, the empire prevailed.
The most severe defeat was when Moscow Czar completely destroyed democratic Novgorod republic of Russians.
Russian nationalists fought against Russia's empire in many people wars led by cossaks Razin, Pugachev, Bolotnikov; they fought together with Polish insurgents ("For your and our freedom"), they fought against Jewish internacionale in Antonov's peasants army in Tambov region...
The empire supported xebophoby and always skillfully controlled international tensions ("Divide & Rule" approach).
But it always were afraid of idea of letting Russians to build their true national state.
People of Ukraine should be happy now after they separated themselves from the power of Moscow. Ukraine promotes nationalism - is Ukraine an empire? No!
Federation of Russia promotes multi-culturalism and fights the Russian nationalism. Is it empire? Yes!
I disagree. Wars in former Yugoslavia were developed on a base of different religious beliefs. Serbs, Croats and Bosnians are all Slavs speaking the same common language. But they are divided as being Orthodox, Catholics and Muslims.
Wars between India & Pakistan were driven mostly because of religion differences.
And many religions (you like it or not) served nicely many empires in this world...
I doubt it too. If you have said A, you must also say B. Proclaiming Québécois as nation, we'rev provoking next question - why Nation without a state? And so on and so far.
Now, please pay attention that ethnic Russians, who are about 80% of Russia's population, are not even mentioned in Russia's constitution as Russian people!
They do not have their national state (even inside Russia, as Tatars, Bashkirs, Yakuts, Chechens, Jews have).
How do you like Putin's remarks like "Pure Russians do not exist" or "Whoever thinks about Russian national state is either an idiot or provocateur"?
Russian nationalism is the only way to build new democratic Russian state! Back to the Great Novgorod? Yes, but with promoting the XXI century progress!
