The Saudis suck at proxy warfare. The Iranians are Hamas, Hizbollah and Fatah. Meanwhile the Saudis are reeling from the ill effects of $35/bbl oil while the Iranians are due to have their sanctions lifted. Nowhere does it suggest that the Iranians sacked the embassy as a state action, while the Saudis whipped their dicks out without even thinking about how it would look.

Saudi Arabia is unstable and scared right now, while Iran, which survived 30-plus years as a rogue nation, is coming into the daylight. MY guess is the Iranians are making a play to provoke Saudi Arabia into shaking itself apart. Something Americans never remember is the Persians haven't fought a war of aggression since the Sassanid Empire. Intrigue and skullduggery? Hell to the yes. You're talking about a country that overthrew their American puppet without the US seeing it coming... and then two years later, capturing the CIA station chief for the Middle East.

I'll bet this goes exactly as far south as Iran wants it to go.
