well why not autonomize the entire region.
Give the people liberty in countries based on their ethnicities
1- These ethnicities would be eternally grateful to us for their independence.
2- This will replace the islamic sentiment with ethnic sentiment.
3- which will in turn trash pan-islamism for good, when the ethnic sentiment is stronger than islamic sentiment.
4- It will rob the countries of the size to pursue global aspirations.
4- It will also rob them of the numbers, infrastructure or the wealth to pursue WMD's or sponsor terror.
I mean isnt this, what was done to russia and yugoslavia
If it worked for russia and yugoslavia, it would also work for iran, pakistan and saudi arabia.
Yugoslovia didn't work out too well...
