President Barack Obama said Sunday that he’s committed to working in “lockstep” with Israel to try to prevent Iran from developing nuclear weapons, as concern is rising in the U.S. and overseas about a possible Israeli strike on Iran that could unleash violence across the Middle East.

Obama seemed eager to calm worries that Israel is on the brink of a pre-emptive attack, even as he continued to warn about the danger of Iran becoming a nuclear power.

“I don’t think that Israel has made a decision on what they need to do,” Obama said during a six-minute, live interview from the White House during NBC’s Super Bowl pre-game show. “We are going to make sure that we work in lockstep, as we proceed to try to solve this — hopefully, diplomatically.”

Obama told NBC’s Matt Lauer that he believes expanded international sanctions on Iran are hurting the regime.

“They are feeling the pinch. They are feeling the pressure,” the president said. “But they have not taken the steps that they need to diplomatically to say ‘We will pursue peaceful nuclear power. We will not pursue a nuclear weapon.’ Until they do, I think Israel is going to be very concerned, and we are as well.”

Obama did not directly answer a question from Lauer about whether the U.S. has blessed any military action by Israel, nor would he say whether Israel has promised to warn the U.S. before carrying out a strike against Iran.

“I won’t go into the details of our conversations. I will say that we have closer military and intelligence consultation between our two countries than we ever have. And my number one priority continues to be the security of the United States, but also the security of Israel,” Obama said.

A series of published reports and statements from Israeli officials in the past week have raised concern that the Jewish state may act in the next few months to try to set back Iran’s nuclear program, which Tehran insists is peaceful but outside experts believe is aimed at building nuclear weapons.

In response to a question from Lauer, Obama said he doubts that Iran is seeking to carry out attacks in the United States. “We don’t see any evidence that they have those intentions or capabilities right now,” the president said.

Obama’s statement was a curious one, since an intelligence community assessment that Director of National Intelligence James Clapper presented to Congress last week said that some Iranian leaders “are now more willing to conduct an attack in the United States in response to real or perceived U.S. actions that threaten the regime.”

Obama said he prefers a diplomatic solution to the Iranian nuclear issue, in part because of the potential impact a military confrontation could have on the U.S. economy and on U.S. troops in Afghanistan and elsewhere.

“But we’re not going to take any options off the table, and I’ve been very clear that we’re going to do everything we can to prevent Iran from getting a nuclear weapon,” the president said.
