Senator Joe Lieberman says the U.S. should consider attacking Iran. Is he right?

No, Senator Lieberman is not right.  We have to exhaust all diplomatic and peaceful options before attacking Iran. We need to press Russia to allow more sanctions at the U.N. How can we do this? A compromise on Kosovo. Stricter and stricter sanctions should be placed. Iran needs to stop now.
