The joint statement by Secretary of State Kerry and Iranian Foreign Minister Zarif that there will be no extension of the talks between the six powers and Iran past the most recent deadline of March 24th means only one thing: a deal has been reached between the U.S. and Iran, which will be announced to the other five participants when the Obama Administration decides it is convenient to do so.
This is the way this Administration operates. It will be recalled that prior to the first agreement for the six to negotiate with Iran concerning its program to develop nuclear weapons, Administration officials met with the Iranians secretly five times in Oman. When the French foreign minister stormed out of the initial meeting of the two sides proclaiming “This is a fool’s deal”, he was subsequently informed that the deal was already sealed by the U.S. with Iran and the French gave in.
