(IsraelNN.com) Iranian parliamentary official Alaeddin Broujerdi said Monday that his country is ready to take “real and decisive” action in response to an Israeli attack on its nuclear facilities. He spoke out while attending a summit in Tokyo.

“Both the U.S. and Israel are aware of the consequences of an erroneous decision,” Broujerdi said. “I believe our response will be real and decisive.”

The Iranian’s comments came a day after U.S. Vice President Joe Biden said his country would not stand in Israel’s way if it decided to attack. “We cannot dictate to another sovereign nation what they can and cannot do,” he said.

Recent reports of preparations for a pre-emptive stike in Iran have come in the wake of growing doubts that the Obama administration's diplomatic arm-twisiting and economic sanctions can convince Iran not to enrich uranium and use it for a nuclear weapon.

John Bolton, former U.S. Ambassador to the United Nations, wrote in the Washington Post last week that America's attempts are doomed to failure and that an Israeli strike on Iran is the only hope to stop Tehran from becoming a nuclear threat to the entire Western world.

Concerning Iran's internal affairs, Iran's Broujerdi defended his country’s crackdown on protestors over the contested Iranian presidential election results, saying the police acted to maintain order. “There is no confusion,” he said. “It is now a totally peaceful situation in Iran.”
