Dear bro Rumi, Salam.
"Islam" (The system of absolute justice, equilibrium regardless of race, color, religion, cast) would be the standard - by which all inhabitants of land are to behave / be treated.
Pakistan is not a name of state, it is just an area named so on this Earth, drawn like others, to do what? you think!
What right at this moment happening in Karachi, Is the beginning of balkanisation of what we use to know as "PAKISTAN". Congrats :)
