It seems that under pressure from the Al-Queda led forces, Iraq's Prime Minister is begging for American support to save his regime.  Suni Muslims are marching towards Bhagdad and if their march is not stopped on a timely basis, they will run over the country which means a terrible future for the Shias in Iraq.  It is unfortunate that the Iraqi government did not agree to the American proposal to grant immunity to the US soldiers before American wound up their operation in Iraq.  I am not sure what Washington is contemplating about this situation, but as an observer of these political chess games, I must say that America should not take any hasty action and probe this situation thoroughly.  At the end of the day, if America decides to get involved, the USA must make sure that Iraq's Prime Minister signs MoU with full immunity to the US forces and any expense incurred by the US forces to protect his regime should be defrayed by the Iraqi government.  Also, there is no need to put American boots on the ground and spell American blood.  It must be an aerial protection with full financial compensation.
