Islamic Chaliphate wannabe first target is to unite All Muslim nations under one banner, so one thing they want to do is to make wars with nearest Muslim country in the world so they can unite Muslim world under one country but will kill 100 million Muslim in the process....
They have always have pessimistic view about democracy because Al-Qaeda and ISIS leaders always emerge from Autoritarian Muslim states/failed states,
The real future Chaliphate stated by prophet Muhammad IMO is actually Muslim Nato where Muslim nation states makes a military alliance where one prominent figure (leader of one Muslim country) may act as the leader similar like any US President become a leader within NATO alliance.
