The short-term American targets include passage of a $48 billion Iraqi budget, something the Iraqis say they are on their way to doing anyway; renewing the United Nations mandate that authorizes an American presence in the country, which the Iraqis have done repeatedly before; and passing legislation to allow thousands of Baath Party members from Saddam Hussein’s era to rejoin the government. A senior Bush administration official described that goal as largely symbolic since rehirings have been quietly taking place already.
