unless oil prices spike beyond $ 100 a barrel for a sustained period of time — well over OPEC's long - term average assumption of around $ 80 a barrel.
Unless, as Michael Levi of the Council on Foreign Relations and The Post's Brad Plumer pointed out, America were to take the extraordinary step of removing itself from the world
oil market entirely, which could lead to its own
price spikes and ignite a trade war.
