Why not partition Iraq as a solution to the conflict ?

why not partition the country for example create a Kurd independent country, give to Kuwait part of the south and the city of Basora as compesation for the 1990 invasion give to Iran most of the eastern part of the country. to annex or give to the UN as a protectorate give Saudi Arabia a large part of the south along the actual border as payment for thier support, and the rest of the west between Jordan and Syria im sure they will taked a small central portion with Bagdad as capital can be left to the shia mayority as an independent state or put it under UN control is my belief that this will make the insurgency internal and external colapse and if not to turn against each other we most remember Iraq was created at the end of world war I before that there was no Iraqui State so lets called a failed proyect and do something diferent there had been precedents for this action the partition of germany afther world wars 1,2 the UN ca't say anithing abouth it becuse they refuse to intervine
