Senator Barack Obama on Saturday said the United States will have to abandon its efforts in Iraq, regardless of the costs, if the Iraqi government does not make serious reforms. "In the absence of those conditions, we're just throwing money away," Obama said during a campaign stop. "We have to be honest that, in the absence of these changes, if these changes aren't made, there is not much we can do" to help the Iraqi people, he added at a later appearance. Obama said there are no good options left in Iraq. "We only have bad options and worse options," he said.
