“It does not change the steps that we are taking to hold Iran responsible for its obligation … including sanctions,” Gibbs said. “We are making steady progress on a sanctions resolution.”…

In a sense, Iran left the Obama administration an out by declaring it would continue producing 20 percent enrichment uranium even as it proposes shipping nuclear material to Turkey. To become official, the deal still has to be agreed to by the same group of nations that pursued the deal last fall — and Gibbs said any move to continue enrichment internally would indeed be a “direct violation” of Security Council resolutions.

“The words and the deeds of the leadership in Iran have rarely coincided,” Gibbs said, adding that the proposal must first be reviewed by the IAEA.

But regardless of how far the deal progresses, the announcement could make sanctions much more difficult to secure.
