Oil isn't an issue anymore.
It definitely was when dealing with Iraq in the early 2000s, and it was a motivator for occupation at that time, but not now.
With the field and rigs established up north we've got that base covered. People like to retort that the oil boom isn't happening anymore up there and they are correct, but that's not the point. At all.
The point is that the infrastructure is there now (and it's being maintained), paid for with what production does come out of there. So even if you're running at 10% capacity, we have tipped the scales in our favor which is evidenced by OPEC squirming in it's chair back in 2017-19. They finally figured out that their days of putting the screws to North America (with oil, anyway) are over. We're the biggest oil producer in the world now, not them.
Once the oil fields got up and running the price fell, and when OPEC saw it they said, "we'll show you fuckers." They cranked up supply and drove the price of oil down to where it was too cheap to produce here so we quit pumping. And we called their bluff, which is A-OK because the infrastructure is there. The expensive part is done. OPEC wants to shut the faucet off and drive up prices? We'll turn ours back on. If you ask me, it's enough of a national security issue that we should be using taxes to maintain oil pumping infrastructure instead of bailing out 9 figure corporations, but I digress.
Don't get me wrong...The Saudis were in the game long enough that they don't have to worry about oil anymore. They've got enough money to get into every other racket (which they are), and that poses it's own set of issues. Iran and its buddies however, they needed oil money and without the US to buy M.E. oil and keep prices up they're in trouble. That's going to cause us a few problems down the road in foreign relations, but domestically we have no real issues. All in all, when you exclude the M.E. oil is pretty much just a domestic security issue. Russia has enough for themselves and enough leftover to sell to Europe and keep things calm. We have enough for ourselves when it's needed and our storage is full.
But the M.E. has too much and not enough market for anyone but the Saudis, so at some point their frustration with that is gonna cause a ruckus to boil over. But it won't be because we need their oil.
