Here's the State Department's terse response to Iran:

United Nations Security Council Resolution 1696 made clear the conditions Iran must meet regarding its nuclear program.

Yesterday the Iranian government conveyed its response to the package of incentives provided on June 6 by the United States, the United Kingdom, France, Germany, Russia, and China. We acknowledge that Iran considers its response as a serious offer, and we will review it. The response, however, falls short of the conditions set by the Security Council, which require the full and verifiable suspension of all enrichment-related and reprocessing activities.

We are consulting closely, including with other members of the Security Council, on next steps.

Meanwhile, a report from the House Intelligence Committee released today says our intel on Iran is so spotty that it's questionable whether the U.S. "could effectively engage in talks with Tehran on ways to diffuse tensions."
