The agreement between Iran and the ‘5 + 1′ group (the five permanent members of the UN Security Council, plus Germany) has been signed.
This seems to be good news for all parties involved for the following reasons: First, the economic sanctions against Iran will be lifted gradually. Second, the break-out options of a nuclear bomb for Iran will be reduced. Third, western and Russian economic cooperation with Iran now has the ability to blossom. And lastly, some people are now able to visualize potential for a more moderate influence by Iran in the neighborhood of MENA.
BUT, it is not quite clear if the agreement will actually be ratified. In Iran the highest leader Khamenei has verbalized some critical remarks, but he seems to be in overall support of the agreement.
The Israeli government is openly ranting about their unwillingness to form any agreement with Iran, just as they have in the past. The most difficult impediment the final ratification is facing is coming from Washington. Congress is very skeptical, and may try to de-rail this agreement after all.
