Considering the long list of complaints Saudi Arabia has had against Iran over the years, many wonder why the Kingdom is supporting diplomatic efforts to end a war that could possibly eliminate a major irritant. The question is a good one, but the answer is complicated. In 1979, soon after the revolution, Tehran put Saudi Arabia in its crosshairs. In a futile attempt to destabilize the Kingdom, it set up terrorist groups that fomented sectarian strife, sabotaged oil installations, attacked security forces and even called for parts of Saudi Arabia to be put under Iran’s control.
