Iran War Ending? Depleting Ourselves Thanks to Iran WarAmerica’s Strategic Petroleum Reserve (SPR) is nearing 300 million barrels, the lowest it has been since 1983. If the war continued, the SoH would remain closed until Americans could militarily reopen it. Shortages in energy products would compel the US government to ration energy as the SPR drained faster than it could be replaced. The more expensive things get due to fuel shortages and the resulting price increases in fuel, the higher the level of inflation.
