President Donald Trump landed in Israel on a groundbreaking direct flight Monday from Saudi Arabia and expanded a core theme of his Sunday speech in Riyadh: the U.S. will stand with Arab nations and Israel against the threats they all agree are posed by Iran.

Meeting with President Reuven Rivlin in Jerusalem, Trump stressed that Iran¡¯s support of violent groups in the region also presented an opportunity for Israel to come closer to countries in the Gulf, some of which don¡¯t have diplomatic relations with Israel. There¡¯s a ¡°growing realization among your Arab neighbors that they have common cause with you in the threat posed by Iran,¡± Trump told Rivlin.

¡°The United States and Israel can declare with one voice that Iran must never be allowed to develop nuclear weapons,¡± Trump said. ¡°Never, ever. And must cease its deadly funding, training and equipping of terrorists and militias.¡±
