A high-level advisor to Iran’s supreme leader said his country is ready to allow “permanent human monitoring” of its nuclear program in exchange for Western cooperation but also warned Iran is prepared to defend itself against military strikes.

Mohammad Javad Larijani, who serves as Secretary-General of Iran’s Human Rights Council and key foreign policy advisor to Ayatollah Khamenei, said the West should sell Iran 20 percent enriched uranium and provide all the help that nuclear nations are supposed to provide to countries building civilian nuclear power plants. He also said the U.S. and the West should accept his country’s right to continue what Iran calls its peaceful nuclear program. In return for cooperation from the West, he said, Iran would offer “full transparency.”

Should negotiations fail and military strikes against nuclear sites in Iran begin, however, Larijani borrowed a phrase from President Obama’s own policy when he said “every possibility is on the table” when it comes to Iran’s response to such attacks.
