There is no such a thing as an Islamic state, because Islam is in its essence is anti-state from what we view as state today.
Ottomans were the closest, but it didn't develop into what we view as a "statE"
Bingo...
Islamic "state" is an oxymoron there was never an Islamic state..
Our minds have become accustomed to the current reality and we will all automatically imagine that since we live in "States" the old khalifates were "states" which they were not..
We need to first de-westernize our brains, our thinking.
Then we need to look at our history without western lens, because in reality we see the past just the way we someone in Europe will see our past.. Which is highly innaccurate..
even our jihadis are westernized in outlook and thinking unwittingly..
all this is the result of centuries of western domination..
once we get our heads around this fact, we will be able to see clearly and then ,
only then can we move forward...
because one cannot go forward without knowing where he has been or where he is right now..
in essence we are all lost..
