I don't disagree with you here per se [although i'd prefer to buy Russian than American] but to say the west is reliant on middle eastern oil and will be in any way freed is a bit wide of the mark in ones view. Namely because petrochemicals being an internationally traded commodity the price is thus out of a nations hands - this may help if Saudi threatened to turn off the taps but to be honest it would still be incredibly damaging to our economies regardless.
