For the second day in a row Iran is attacking Gulf state infrastructure. Yesterday an Emirati oil rig was targeted, today a drone strike on a Saudi ARAMCO oil refinery in Ras Tanura. Couple that with targeting 5 oil tankers in the Strait of Hormuz and it's clear that this is a 'throw the kitchen sink' type of situation as Tehran is looking to create a regional war, create rifts between the US and its Gulf allies, drive up oil prices and thereby create additional pressure on DC to call off the rinsing/ regime change op.
It could very well be their best chance yet if they don't come out on top the results will equally be exponential.
