"I am still optimistic because I think, sooner or later, all the parties will realize that there is no other option but to go back to negotiation, that Iran will understand that they need to be transparent," he said. "If they want to restore the confidence of the international community, they need to take confidence-building measures."
In testimony to the U.S. Congress, Undersecretary of State Nicholas Burns declared that Iran "directly threatens vital American interests" and that the members of the UN Security Council were planning a "concerted approach" that "gradually escalates" on Iran.
Earlier, Washington said Tehran risked unspecified "consequences" if it does not halt its nuclear-research activities in defiance of the international community.
Speaking to Journalists in Vienna, the Deputy Secretary of Iran's Supreme National Security Council, Javad Vaeedi, threatened "harm and pain" against the United States if it is referred to the Security Council for punitive sanctions.
At the UN headquarters in New York, Russian Foreign Minister Sergei Lavrov said Moscow opposes both Security Council sanctions and military action as a response to the Iranian nuclear crisis.

Economic sanctions could further undermine Iran's already shaky economy (Fars)
MOVING TOWARD SANCTIONS: If the United Nations Security Council imposes sanctions on Iran, domestic support for Iranian President Mahmud Ahmadinejad will wane, according to ALEX VATANKA, Eurasia editor for Jane's Information Group.
Vatanka told a February 24 RFE/RL briefing that "economic sanctions will hurt the average Iranian" and, consequently, many "will blame the ruling clerics" for making life difficult and "impairing the country's long term development."
Vatanka said sanctions would be a serious challenge to the Iranian government. If harsh economic sanctions were imposed, Iran's poorest population will be hurt the hardest -- and might react "as they did in the 1970s and protest in the streets." Sanctions on travel, Vatanka said, would hurt a many Iranians because "Iran is a nation of small traders" who depend on the ability to travel to earn an income. According to Vatanka, unemployment in Iran is estimated at 30 percent, "so small trading is essential to survival." Although current U.S. sanctions "haven't worked," he said, "Iranians fear an oil embargo." He stressed that "oil revenues are a major part of the economy, so it is critical to look at this sector."
Should negotiations with the European Union and the UN fail, Vatanka believes that Iran would follow a "North Korea model," since Ahmadinejad's base of support among the "Islamist militias" has been "urging withdrawal from the NPT [Nuclear Non-Proliferation Treaty]." The Iranian government's "tactic" so far, Vatanka said, is governed by the belief that "by shouting the loudest, you'll get concessions [from the West]."
