Imagine that.
Kick out all the illegals, visa overstays and ban the invaders and the US won't need as much Saudi oil. More than a decade ago, it was guesstimated 1 in 8 people in the US was an illegal. At minimum, we'd require 12% less oil. Considering all other aspects, we might could get it down to 20% less demand.
It isnt just about the oil...its the monetary system to be used for oil purchase (US dollar) its the billions in US treasuries held by Saudi (through alliegence Saudi and China could collapse the US economy in a single day), militarily (with a Chinese, Russian, and Saudi bankrolling them) itd be childs play.
Much more than oil
