Israeli Prime Minister Benjamin Netanyahu said on Twitter Wednesday that he was meeting with Arab leaders to further the “common interest of war with Iran” — but then quickly deleted the bellicose statement.

“I am going to a meeting with 60 foreign ministers and envoys of countries from around the world against Iran,” Netanyahu wrote on Twitter from Warsaw, Poland, where a two-day, U.S.-led summit began Wednesday. The “Ministerial to Promote a Future of Peace and Security in the Middle East” was meant to center on what the administration considers the biggest roadblock to such a future: Iran. But under pressure from European allies, the United States broadened the focus to the entire Middle East.
