Iraq- A way to clean up the mess but will George Bush go for this

I think the mess in Iraq can be cleaned up if George Bush accepts publicly that it was a mistake to start the war in the first place and seeks the apology of the Iraqi people. He can then bring Iran and Saudi Arabia together to a peace conference under the auspices of United Nations. USA can get the backing of Saudis to help Iran develop its nuclear technology for energy purposes (just as it was ready to do with North Korea) and if necessary get the Saudi consent to Iran having a couple of nuclear warheads. The Saudis can also be persuaded to use their oil money (which is increasing daily thanks to the higher oil prices which is the direct result of the war and the uncertainty it has brought) to help in reconstruction of Iraq. The Iranians, in return for the co-operation they will get to become a nuclear power (which is the Iranian ambition) will get the Shiites in Iran to make peace with the Sunnis and persuade all of them the Sunnis and Shiites and the Kurds to join together in a coalition government. The United Nations will appoint a monitor who will be sort of a Regent to make sure the coalition government works properly to restore peace, law and order in Iraq and use the aid money from the world (principally the Saudis and the Americans) to rebuild Iraq. The logistics will be worked out and implemented by the United Nations. This will be the most massive reconstruction after the renewal of Europe under the Marshall Plan and the whole world can participate in the re-building and help the Iraqis.
Will George Bush consider this option and work for peace?
A Million or is it a Billion or Trillion dollar question?
