What “agreement” are they talking about? I don’t think Iran ever said they had agreed to anything. Obama and Kerry are the ones who said they’d reached an agreement.
Indeed, the State Department has now admitted as much. No deal has been signed...there are a number of "technical issues" yet to be negotiated...the clock doesn't start running until those issues are resolved...and everybody actually signs on.
In the meantime, of course, we've already handed over the keys to the frozen assets and lifted the sanctions.
It's evident why Obama and Kerry were in such a rush. Obama's TV appearance late Saturday announcing "Peace In Our Time" turned the focus of the Sunday morning shows from the Obamacare embarrassment to the Iran "success".
