Re: Islamically can you join a national army...
Very good question.....but I don't know the complete answer. My father was in Pak army.....but I will never let my children join any national or religious army in the current situation of the world. why? Because as you said nationalism is haram in islam....
Why would nationalism be haram in Islam. We are the best among the nations aren't we?
I think this would be subject to what the nation represents i.e. ethnicity, color, race, religion, geography etc.
