PANews reported on May 18th, citing Iran's Tasnim News Agency, that sources close to the negotiating team stated that despite some changes in the new US document, substantial differences remain due to US greed and lack of realism. Iran firmly demands that the US pay reparations for the war. Frozen Iranian assets must be returned to the Iranian people in a clear and concrete manner. US demands in the nuclear field are purely political pretexts and contrary to the rights of the Iranian people. As previously announced, Iran has no intention of developing nuclear weapons; this US claim is merely an excuse and deception. Furthermore, the US's continued attempt to link war-ending negotiations with the nuclear issue is illogical, and Iran will not agree to it. The US needs to understand that Iran will not agree to exchange nuclear commitments for an end to the war under any circumstances.
