Yes, I understand that, perfectly.
Yet that also works in reverse, and turnabout is fair play.
Consider this: the one nation so seriously affected by this, is the one nation with the ability to shut off mid east oil, Israel.
If the US won't make nuclear Arabs and Persians go away, Israel can make the mid east oil go away for the US and Europe, and do a lot of damage to the nuclear ragheads.
Russia, China and India would be thrilled at the shift in power, China and India would chaff at the loss of US market, but US market competition would fall to minimal worldwide.
