Re: Islamically can you join a national army...
Well, if you are just a muslim and not a nationalist muslim then there should not be any conflicts based on race, colour or sects.
sorry race, ethnicity and sect has little to do with nationalism.
lets not mix these all up together.
teh correct statement woukd have been, if you are just a muslim and not a sectarian muslim, or a ethnocentric muslim, or a racist muslim, then there should not be any conflicts based on race, ethnicity or sects.
again, more disputes, fights and tension based on race, ethnicity and sect than nationality aming muslims.
