Iran's New Leader Just Said Something That Should Terrify Every American (Ad)

Iran's Supreme Leader has declared the Strait of Hormuz closed as leverage against the U.S. - and with 40% of the world's oil passing through that corridor, crude has already crossed $100 per barrel. History shows gold surged 571% during the 1973 oil crisis and 425% in 1979. Today, the U.S. holds 8,133 tonnes of gold valued on the books at $42.22 per ounce - while gold trades above $5,000. American Alternative Assets has released The Great Gold Reset report detailing what this gap could mean for investors.tc pixel
