President Obama says it’s not personal with Israeli Prime Minister Benjamin Netanyahu — it’s strictly business.

“When I’m with Bibi, we have good conversations,” Obama told Israel’s Channel 2. “They’re tough, they’re forceful — we disagree, but I enjoy jousting with him. I do.”

Obama granted the interview in part to speak to an Israel audience on behalf of one of the things he and Netanyahu argue about: The proposed nuclear deal with Iran. The interviewer seemed to question Obama’s claims about his relationship with Netanyahu, saying the president’s “jaw was locked” during one seemingly tense meeting.

“Oh, no,” Obama said. “I think I was probably just hungry and waiting for lunch.”
