Today's announcement reflects the Iranian leadership's continuing violation of international obligations and refusal to address international concerns. This approach has not brought Iran international respect or accolade but rather increasing censure and sanction.

As President Bush said on the eve of Nowruz, Iran's leaders have isolated a great country. There is a better way forward for Iran to achieve its right to civil nuclear power: compliance with its international obligations and acceptance of the June 2006 offer by Europe, Russia, China, and the United States.

The June 2006 offer contains important technical, political, and economic benefits for Iran. It would help Iran attain what its leaders say they want: nuclear energy, state-of-the-art technology, and assured access to nuclear fuel.

Today's announcement shows clear intent to even further violate Security Council requirements. Negotiation, not escalation, provides the best path to international respect and regional security.
