Republican presidential candidate Chris Christie on Tuesday presented his plan of regime change as the only viable policy that the next president will have to deal with Iran in the day after the nuclear deal is expected to be implemented.

In an appearance on Fox News’ “Hannity” program, Christie said that other than threatening the Iranians with military action in order to prevent them from acquiring nuclear weapons, he will rehash a previous game plan of regime change in Iran on day one of his presidency if elected.

“Two things I’ll say on the first day to the Iranians, the first is you will never have a nuclear weapon and if that means taking military action to stop it, we will, and second, that the United States’ official policy is for regime change in Iran, regime change, that’s our policy,” the New Jersey Governor said.

Christie said his plan will be supported by Israel, Saudi Arabia, Egypt, Jordan and the Emirates, “because they do not want to see a Persian empire across the Middle East which is what Vladimir Putin and the mullahs in Iran are looking to build.”

In August, Christie refused to say what he would do as president if Congress fails to block the Iran nuclear deal. “Over the past six years the people of New Jersey know that when I think something is a bad deal, I act on it. That is exactly what I would do,” he told reporters during a campaign event at Rutgers University’s Chabad House in New Brunswick. But on Tuesday, Christie stated that the next president “better be prepared” to destroy Iran’s nuclear facilities by air, “and I will be. I’ll be prepared to do it.”

Over 100,000 people came out to rally led by Maryam Rajavi, the head of the Iranian opposition, in Villepinte, France, on June 13, 2015. Rajavi is President of the National Council of Resistance in Iran (NCRI) and the People’s Mujahedeen Organization of Iran (PMOI).At the rally, former NYC Mayor Rudi Giuliani declared, “I will not support a presidential candidate who will not support a regime change in Iran.”
