if i were to carve the region up, i'd do it in the following manner.
1- For pakistan, I would first of all declare secular sind and baluchistan as independent countries.
This would rob Pakistan of all the mineral wealth and all it's sea ports.
I would then use these two independent states to isolate and squeeze the militant pakhtoon and punjabi areas for a few decades, much like libya to destroy their militant and fanatical sentiment.
this should be followed by a deporation of militant pakhtoon and other fanatic populations from moderate islamic states.
2- For iran, i would again proceed with an azeri and baluchi cession first. this would rob iran of around a fourth of its population and give us control over iranian sea traffic passing through hormuz.
This could be followed by merging of areas of iran into turkmenistan, afghanistan etc. the persians only make up 51% of the iranian population, the rest could be incorporated into other states along ethnic lines.
3- saudi arabia similarly should be carved into small states the size of qatar. saud had to unite various tribes to create saudi arabia, it can be broken up into small states the same way.
These three countries are the source of all islamic terror, political and WMD efforts.
A break up like that of former yugoslavia, would replace the islamic sentiment with a strong ethnic sentiment and rob these countries of the resources to destabilize the world.
4- whatever the divisions care should be taken not to create any states that might emphasize islamic sentiment.
5- However before we proceed with any of this, The WMD might of both iran and pakistan needs to be addressed.
india could address pakistan, while israel could address the iranian threat.
The US could then buffer israel and India from possible international repercussions.
6- Since this break up would take a while to materialize, i suggest we use the threat of this break up to force pakistan, saudi arabia and iran to crackdown on and destroy the terror they created over the years, shut down all religious schools, outlaw parties like jamiati islami or else we would break them up into small insignificant states.
since pakistan and saudi arabia created al qaeda and wahhabi terror and political movements, they'd be the most effective agents of destroying these movements. Similarly since iran created hizbollah and all shiite terror and political movement, iran would be the most effective agent for destroying all shiite terror and political movement.
we need to threaten these countries with their break up, unless they destroy the terror and political movements that they created.
7- All of this should be accompanied by a clean up within western intelligence of islamist influence, to jettison all islamist elements, to create a new cadre of western linguists and a new cadre made of western, latino and african operatives to lead teams that would use muslims only as guides. It might also be a good idea to do away with islamic intermediaries and for western operators
to run all islamic moles directly to prevent them from forming an islamic lobby.
ghaffar khan's movement consisted of a very few people, while pakhtoon fanaticism was rampant even back then.
You'd find that back in 1948, during the heydey's of ghaffar khan, kashmir was invaded by savage pakhtoon hordes. these savages are at the source of not only all recent terror in the region but also responsible for the kashmir problem.
besides if you take some time and read ancient indian history, you'd see that pakhtoons and looted and plundered india for as long as history can remember. I think the first barbarian's name was ghazni or suri or something. I read about it in some publication from the british-india library or something
