To answer the both paragraphs: I see your point and it is shameful to hear how he has been treated. But at the same time, as Muslims in today's world, we are not supposed to be nationalists as nationalism goes against Islam. This is not to say that Muslims should throw away their passports and say that they are from a non-existant united Muslim state, not at all. This simply means that a Muslim should not fall into the foolishness of putting his nation first at the cost of the Ummah (sorry, but especially if he is from a majority non-Muslim state). In regards to Muslims staying away from nationalism, this is so that one does not become too prideful of being from a certain state, even if it is a Muslim-majority state, and believe his state and its people to be the best.
Also, as Muslims, when the government of our country (whether of a Muslim-majority or non-Muslim-majority state) takes a good initiative that does not go agaisnt our faith, we are obliged to co-operate. But the opposite also applies, if a state takes an initiative that goes against Islam, Muslims are obliged to appoint someone to advise the leader(s) of the country in private to avoid fitna. I realize this advising process is easier is Muslim-majority countries with Muslim heads of state, but Muslim leaders in non-Muslim-majority states with non-Muslim heads of state should also voice their concerns about the initiative and try their best.
I know this may seem somewhat off-topic, but I hope you can see how it applies to Muslims regarding avoiding nationalism while at the same time not cutting oneself away from the government of that country entirely, whichever country it may be.
