of course not. why should they? Who's gonna stop them now that Iraq is powerless?Iran is a spoiler.. They do not want peace in the ME or even a just peace for the Palestinians.
My personal opinion ( but never have been there) is the the Palestinians are just pawns for the arabs and Iran.
Nobody really cares about them
The Saudis care about the Palestinians and have supported them financially since 1948.. but the way forward is not HAMAS..
