You are not thinking and on top of that, you did answer the question as to how the war with Iran is going to help YOU.
Having more oil to sell does not mean more money is made. If you can sell 3.2 million barrels of oil at $120 dollars a barrel you make $388 million dollars but if the price of oil is at $80 per barrel and you sell 4.8 million barrels at $80 per barrel, you make $392 million. Supply and demand, you know how that works, don’t you?
Why would anyone want to sell their supply if they make no extra money?
