The US Defense Secretary Leon Panetta had this to say:

"I think the pressure of the sanctions, I think the pressure of—diplomatic pressures from everywhere—Europe, the United States, elsewhere—is working to put pressure on them, to make them understand that they cannot continue to do what they’re doing. 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."
