Political analyst and nuclear physicist Ali Khorram said here on Saturday that achieving scientific and industrial development is the key for Iran's success in its nuclear talks with the European Union. Until six months ago, not many people were aware of Iran's scientific progress and nuclear status, and this also influenced the process of the nuclear talks, Khorram told the Mehr News Agency. But after International Atomic Energy Agency (IAEA) Director General Mohamed ElBaradei's reports revealed Iran's scientific and industrial expertise in regard to the nuclear fuel cycle and centrifuge construction, its nuclear status actually served as an engine for Iran's diplomacy, he said.This scientific development made European countries and the United States realize that they could no longer persuade Iran to abandon its nuclear fuel cycle program, Khorram stressed. It also proved that threats to attack Iran's nuclear installations would not be effective, since nuclear technology has taken root in Iran, he added. Khorram, who served for years as Iran's representative on UN disarmament and human rights commissions, noted that the fact that the Islamic Republic made it known that it might withdraw from the nuclear Non-Proliferation Treaty (NPT) was another factor that helped expedite the process of nuclear talks. He stressed that the right to withdraw from the NPT is stipulated in the treaty as a clear right for all signatories, adding that a country which withdraws from the NPT has committed no wrong according to international law.
