WASHINGTON In the Middle East, your enemys enemy is your friend.

For Israel, Saudi Arabias growing willingness to confront Iranian influence in the Middle East presents an opening for an awkward alliance. As the kingdoms dynamic new crown prince, Mohammed bin Salman, tries to rally an anti-Iran coalition, Israel  with the blessing of the Trump administration  is presenting itself as a willing and able partner.

The appetite for cooperation between two of Americas closest allies in the Middle East has grown in recent years as their security interests have dovetailed. Both Israel and Saudi Arabia view Irans growing influence in the region as an existential threat and want to squash militant Islamist groups like ISIS and Irans main proxy, Hezbollah.

A U.S. official who witnessed a Saudi and Israeli official hold a closed-door meeting together recently said such informal meetings have been taking place for at least five years.
