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

Trump's gold order: the announcement they won't put on the front page (Ad)

On August 15, 1971, Nixon interrupted prime-time television and ended the gold standard in 15 minutes - no debate, no vote, one executive order. Gold tripled within three years and climbed 20x over the following decade. Trump holds that same executive authority today, and his advisors are openly saying a reversal is on the table. There are two ways this plays out - both move gold in the same direction. A free briefing breaks down exactly what Nixon did, why Trump is positioned to act, and how to move your 401k into gold before any announcement - tax free.tc pixel
