Ok but just logically. What’s more important? 80% of your economy? Or more expensive energy? Whatever we believe about the latter, the former is existential.
Logically they are the same thing. Economy makes things with energy.
~90% of government revenue that has no substitute?
Or ~10% of oil imports for which there are a plethora of alternatives?
You said "a plethora of alternatives". Are there, really? Can you (or someone) show that others are ready and willing to supply that much oil?
Losing Iran's oil probably causes a world war.
