Well if you are sitting at 40-50% and you actually still get oil from a lot of different countries it isn't a dire situation at all. Its not like all of a sudden we aren't getting oil from a variety of other countries. Its more like a slow drain on reserves while other sources start producing. I would also wager that its just price suppression before midterms.
OP's comment was that we are at 0 and nothing left. I pointed out that they were being hyperbolic or that they don't understand the strategic reserve (or both).
