Saudi budget is being blown apart by this desperation to burn the US shale producers. Not sure how long they can maintain it internally politically. They are having to raise/ levy TAXES (!) in the KSA to try and recover some of the deficit. They are running out of cash reserves. I think the KSA needs to make peace that shale exists and the USA is now a net exporter end close the taps a bit. Their strategy isn't working for them, let alone the rest of us!
