Following is the text of the interview:

As you know US Congress passed the bill of the revision in Iran nuclear agreement. What is the purpose of this bill when two sides are negotiating?

There has been strong sentiment in the United States that the US Congress should have a role in approving or disapproving the agreement on Iran's nuclear program, once negotiation of the agreement is complete. The bill provides a procedure and a schedule for Congress to play such a role, calling on to enact a possible resolution of approval or disapproval as early as the first 30 days after completion of the agreement.


Why did President Obama change his mind and accepted to sign the bill?

The president would have preferred not to have such a bill. It is unnecessary, and some opponents of an agreement with Iran have been looking to the bill as one more possible way to defeat the agreement. But further negotiations among members of Congress altered the bill so that it is not as damaging as the original version would have been. Some ‘poison pills’ that could have killed the agreement have been removed. Some analysts believe that the bill in its current version actually works to the president's advantage. It sets aside the idea, which some opponents of the nuclear agreement have been pushing, that the agreement would have to be in the form of a treaty that would require a positive two-thirds vote of the Senate to be adopted. Under the current bill, the administration only needs the support of at least one-third of either house of Congress to prevent any Congressional action killing the deal.

What is the impact of this bill on negotiations between Iran and the 5+1?

The bill does still restrict the president's ability to offer any sanctions relief in the first couple of months after an agreement is signed; possibly this will inhibit what the negotiators could agree to. Beyond that, however, it should have no direct effect on the negotiations.

Will this bill have a negative impact, on one hand, on integrity of 5+1 and on the other hand, on Iran?

The principal possible effect may be to increase Iranian doubts about the willingness of the United States to live up to its side of any agreement. The bill is a reminder that no matter what the Obama administration may agree to, there still is a possibility that the Congress may kill a deal.
