Bush: Unclear when Iraqi forces can take control

President George W. Bush said Friday that it's not yet clear when Iraqi forces will be able to take control of their country's security, a key step in bringing US troops home. Making that determination depends on an assessment of the new government in Baghdad, which just on Thursday installed a new defense minister and other top national security posts, Bush said. "I think we'll get a realistic appraisal about the capacity for standing up Iraqi troops as this new government begins to function," the president said, appearing here with Danish Prime Minister Anders Fogh Rasmussen, a staunch US ally in Iraq.
