With Iran, probably the biggest foreign policy challenge for the next president, the Bush administration plans to take a helpful step in mid-November by announcing the opening of a U.S. interest section in Tehran. That will break the ice and make it easier for the next president to begin the kind of dialogue with Iran that’s necessary. The administration had planned to announce the interest section in August, but Russia’s invasion of Georgia and worries about U.S. election politics intervened. Administration officials assure me that it’s still coming.
