The Saudis are bullies. Hope they get karbashed. They wouldn't last a day against Iran anyway if daddy america stays out of it. Iran needs to strengthen its ties with Russia and China so they can come in if America tries to help out the Saudis.
They keep on provoking Iran because they want them to start the war first so that they could justifiably involve the US in it.
However if the Saudi's declares war and start attacking first then they are on their own (excl Saudi subordinates like Egypt, Bahrain & etc). If it's the latter case then Iran could easily karbash them even with the recent weapon sales from the US.
"Waaah! Why must we have our dominance in the Middle East challenged by an intellectually and culturally rich historical power??...We already have to share control with the darn Jews, at least let us have full dominion over the Muslim world!!! *another tantrum* We're more than willing to sell out Islam and spread Wahhabi supremacy in return for some power!!! Anyone who questions our position/status must be punished, how dare those filthy Persians?!!". The entitlement and arrogance is so off-putting.
