Their insane hatred of Iran has brought them together.
Is it insane to hate a regime that explicitly promised to erase you off the map? We're sure getting a lot of compassion from leftists like you. Maybe you should feel how it is to be threatened with genocide.
I thought the Saudis (and really most Arab countries in the area) had also pledged to erase Israel from the map or some variation on that?
I guess it's nice that they have dropped that.
From what I understand, the Saudis never really cared too much about destroying Israel, at least compared to the other Arab nations. Support for the Palestinians was for a while more important to secular leaders like Nasser and later Saddam, two of the main anti-Israeli hardliners, as part of the pan-Arabist ideology. The Saudis did take some steps though to keep up appearances in the Arab world, like taking part in the 1973 oil embargo and sending a small force during the Yom Kippur War, but their alliance with the US and the fact that they were on opposite sides of the nationalist Arabs in the Arab Cold War prevented them from doing much to bother the Israelis.
