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.
It's all interests, of course. The Saudi might've not been for destroying Israel for some time now, but they're just as vile as ever. It's just that Israel can't afford to rebuke powerful neighbours willing to cooperate, not in this neighborhood.
A short term cooperation for an immediate goal is one thing, but making an ally of a country that is the leading funder of groups devoted to annihiliating you is foolish. And Israel should know better since they did exactly that by making a friend of Hamas (nee Moslem Brotherhood) over al-Fatah back when Palestine was secular (relative to the region). Its kind of like Likud making friends with US dominionists awaiting the second coming. ...or Reagan eliminating bars on funding more extreme elements of the Mujahadeen in Afghanistan.
