Iran appears to be hurtling toward a tipping point. In recent weeks, the Islamic Republic has attacked oil tankers in the Strait of Hormuz, shot down a U.S. military drone and announced plans to execute 17 suspected U.S. spies. One factor behind the recent moves? Iran's economy is struggling under the weight of U.S. economic sanctions. The oil-producing country has been the target of U.S. sanctions for decades, and they've taken a major toll on its economy. Inflation is now rampant, and investors remain wary of directing capital to the country.
