Iran is ready to take "real and decisive" action if Israel attacks its nuclear facilities, a senior Iranian parliamentary official said Monday. The remarks by Alaeddin Broujerdi, the head of Iran's parliamentary committee on national security and foreign policy, came after US Vice President Joe Biden signaled that Washington would not try to prevent any such Israeli assault. "Both the US and Israel are aware of the consequence of an erroneous decision," Broujerdi told reporters at the Iranian Embassy in Tokyo. "I believe our response will be real and decisive," Broujerdi said. He declined to elaborate.
