That's what the Strategic Petroleum Reserve is for, and what energy independence was supposed to for - to insulate (not isolate) American from MidEast Petro-economics and Petro-diplomacy.

We are less dependent on Middle East oil than India, Japan, China, and Europe.

Other powers have a greater stake in Persian Gulf oil than America.

OK, lets pretend that none of the oil the US uses comes through the Strait of Hormuz. So Iran interdicts oil used by "China, Japan, India, Europe" and the rest of the world. Worldwide supply shrinks, while worldwide demand does not. Supply-and-Demand happens and the entire world is paying much higher oil prices, including the US.
