Prime Minister Benjamin Netanyahu said that the US and Israel will resume military action against Iran if needed during an interview with CNBC on Wednesday.

"I think there’s a tactical game that is being played," he told CNBC's Sara Eisen, adding that he would leave the ball in US President Donald Trump's court if escalation was necessary. 

“Iran surely knows what [Trump] has said, that if necessary, there will be a full-scale return to military action. It’s a president’s decision, Israel is ready, and the US forces are ready.”

Notably, Netanyahu gave an open-ended answer on what he believes should be in a ceasefire agreement, conceding that “it’s an open question on how the war should end.”

He went on to acknowledge his tense call with President Trump earlier this week, saying that the two have “tactical disagreements,” but highlighted that  they “agree on the main things.”

“Sometimes we have, as in the best of families, you have these tactical disagreements,” he said, adding that “we always find a way to work them out, and we do so as great friends.”

Netanyahu added that he and Trump speak every two days and that the pair have “have common goals ... we want to achieve them.”

He then said that he thinks that the Islamic Republic had been "enormously weakened" but did not state if he thought regime change was imminent.

“You can’t quite predict when a regime like that goes under,” Netanyahu said. “You didn’t predict it in a number of cases: Not in Romania, and not in the fall of the Berlin Wall, and nobody predicted it, but it happened. Why? Because the cracks were propagating underneath.”

“In fact, you have enormous cracks right now in Iran, and you can’t predict when it’ll happen,” he added. “But I said yesterday in a public forum here ... ‘Look, I believe that ultimately these cracks will propagate and the regime will fall, and we’ll do our best.’”

“I think that we have to help the Iranian people to bring down this regime, and that hasn’t changed, but it’s not going to happen, you know, exactly at the moment of our choosing."
