President Donald Trump says that Israel would be the “leader” of a potential military strike against Iran if Tehran doesn’t give up its nuclear weapons program.

Trump made the comments ahead of this weekend’s scheduled talks involving U.S. and Iranian officials in the Middle East sultanate of Oman. Trump earlier this week said the talks would be “direct” while Iran has described the engagement as “indirect” talks with the U.S.

“If it requires military, we’re going to have military,” Trump said. “Israel will obviously be very much involved in that. They’ll be the leader of that. But nobody leads us, but we do what we want to do.”
