The U.N. nuclear supervisor is flying to Tehran today. He is seeking a deal to inspect sites suspected to be developing nuclear weapons. Iran may hope to persuade the United States and other Western nations to lift sanctions and minimize threats of war. While I would like to see progress, I won’t hold my breath. Iran may only be buying time as it continues to develop nuclear weapons. I’m afraid the the sanctions and the threat of war must remain on the table until the inspectors have seen and cleared all Iranian sites suspected of developing nuclear capability.
