An article in today's Jerusalem Post about the President's position on Iran that quotes unnamed sources -- quoting unnamed sources -- is not worth the paper it's written on.
Let me respond by reaffirming the policy of the Administration: We, along with our international allies who want peace in the Middle East, remain opposed to Iran's ambitions to obtain a nuclear weapon. To that end, we are working to bring tough diplomatic and economic pressure on the Iranians to get them to change their behavior and to halt their uranium enrichment program.
As the President has said, no president of the United States should ever take options off the table, but our preference and our actions for dealing with this matter remain through peaceful diplomatic means. Nothing has changed in that regard.
