astounding!  

Reading comprehension, and education Crowbot.

you obviously lack both. 

The US has the "extraordinary privilege" ( Charles DeGaule once remarked) of being the world reserve currency.

we are at the top of the heap, the other world currencies don't buy oil -- they must convert their currency to DOLLARs to buy OPEC oil. 

Since the Federal Reserve can print money (qualitative easing) they can affect global inflation directly, devaluing the dollar AND every other country's currency-- because those countries must also devalue their currency or their exports are too expensive for the worlds biggest consumer market-- the US. 

And because of the US-Saudi OiL Cartel, these other countries must hold large amounts of DOLLARS in "reserve" to stabilize their oil costs. Energy cost also directly affects inflation. 

Now the BRICs nations also produce oil, snd sell it in other currencies than the US dollar. Their price point (profitability) was around $100 a barrel, last time I looked. Thanks to Creepy Joes oil starvation policies it's around $130 a barrel currently, and rising.

We import Russian oil. Europe depends on it. it's as if Putin told the West: "You want inflation? Here you go! Great for my private oil production ( Lukoil) and whatcha gonna do about it, Brandon?"

A reasonable bluff.. Global poker game. (The other guy thinks he's playing "spades!) 

IF the Saudis were to sell some of their oil in Chinese Yuan the nations of the would start hoarding Yuan, dumping dollars. That would cause inflation and shift that "extraordinary privilege" from the US to China. 

Realize ( as Putin clearly does) that NATO is simply the military action arm of global capitalism, as presently led by the US central bank. If China gains that power, it can use both ECONOMIC and Military coersion to control access to markets snd resources, while US / NATO strength and dominance in the world would wane, to say the least.

The Saudis are a bunch of spoiled camel jockeys that we ( using petrodollars) made wealthy beyond their wildest dreams. They are surrounded by Arabs who weren't so fortunate, and so they have depended  on this US alliance to protect their grid-square. Until now. They would signal a break from their need for US military security if they joined a pact with Russia and China. If we were to respond militarily it could be the beginning of Armageddon-- read about it in the Old Testament Book of Daniel.

But how can I expect a fool who apparently doesn't understand the fundamentals of global economics to appreciate biblical prophesy? Theology aside, The Saudis have postured breaking with OPEC before, maybe their bluffing this time too. 

But since demented Brandon thinks the "Queen of Spades" is a TRUMP CARD ( pun intended) in this game of global high stakes POKER ., I'd say the Saudis ( holdin a pair of 2's and 4's ) know it too. They're scared, and may be trying to get ahead of the curve, and hedge their bets, trying to be on the winning  side of this "Great Reset" idea the Western Oligarchs have foolishly enacted, and are rapidly losing control of ..,

Got a bomb shelter picked out yet? 

Useful idiot!
