Won't nationalism be redundant under a religious state?
Lets give an example of Pakistan. Most people are Muslim. If people stopped being nationalistic and were more religious they would still support Pakistan (since its a Muslim state) but with an added factor of Godwariness (and hence treating others well), being upright in character, giving much charity, etc?
I hope I can articulate properly here.
Usually nationalism is not redundant in a state with religious people. It can be redundant if an alternate is being projected or enforced. e.g. Islamism can be used to shun off nationalism. And that's exactly what Al-Qaida does. i.e. All muslims belong to one nation and they do not believe in borders and want to bring all muslims under one caliphate - the emphasis to use violence indiscriminately to achieve that objective is what make them terrorists in the eyes of majority of world -- but other than that they are simple Islamists.
If nationalism is taken out from Pakistan (or any other state) then that country can hardly survive. thinking of people living in Pakistan as nation and willing to serve for it, not only in social welfare but also to defend it.
TTP or other Islamists don't believe in Pakistan actually, they think this nationalism theory and this country created on that is invention of the English,,, its westernized founder, hence an evil thing.
Pakistani soldiers fighting other Muslims terrorists or fighting Muslims in Indian army need a motivation to fight those enemies and that motivation is to defend their country i.e. nationalism. If they were thinking all muslims equally, why would they want to fight TTP,, and would rather accept authority of TTP.
as said Pakistanis are confused in nationalism and religion. When India would attack Pakistan,, dropping bombs even in a deserted empty land near Lahore causing no casuality, whole country's nationalism would wake up (And that behavior is justified).. but if it is Islamists that killed 50,000 Pakistanis,, they would still be looking any excuses in not believing that the killers are also Muslims and if they could be treated as enemies, despite the fact that their leadership is from middleast (and here is where the problem arises).
