LEON PANETTA, U.S. SECRETARY OF DEFENSE: Are they trying to develop a nuclear weapon? No, but we know that they're trying to develop a nuclear capability, and that's what concerns us. And our red line to Iran is: do not develop a nuclear weapon. That's a red line for us.
BOB SCHIEFFER, FACE THE NATION (CBS): What would happen if Israel does decide to take this matter into its own hands? And what would be our reaction and response to that?
PANETTA: If the Israelis made that decision, we would have to be prepared to protect our forces in that situation. And that's what we'd be concerned about.
