Map: a “New Middle East”

Well that really upsets two nuclear powers[Israel and Pakistan], the two largest and most powerful states between them [Turkey and Iran] and the Saudis [who are threatened with losing both the bulk of their oil if I read the map correctly and control of the Muslim holy cities. The Kurds will be happy, provided the assorted Kurdish groups can agree on a common programme as I believe their political views vary considerably, but pretty much all their neighbours will be after their blood. The Arab Shia state seems to have a hell of a lot of Iran, well beyond where the Arab minority lies IIRC. Not sure why Kuwait survives in this case?

Yemen is difficult enough to hold together as it is already so not sure if this enlarged one will be any better? Similarly Afghanistan may be even more fractious.

Agree with ss that I can't see this reduced 'Persia' being likely to be friendly to the west, especially if its the west imposing such border changes.

Its possible that if you had a powerful coalition imposing those borders and preventing assorted groups using force to object then in a generation or two and if the assorted new communities start getting stable government then things might improve compared to now but I think it would be a long and difficult task to get the changes accepted.

  The old secular Israel of the 60's and 70's probably would be happy with that if it meant a durable peace.  However nowadays the religious parties are a hell of a lot more influential.  To them much/all of the west bank is sacred territory.  Plus the Golan is important for covering the north of the country against Syria which barring significant changes looks to be a potential haze, one way or another for the foreseeable future.  [Albeit not in the short term as the regime recovers from a bloody civil war.  Not to mention what they decide about the Kurds once IS is removed as a visible player in the area.]
