Iran's control of the Strait of Hormuz is complicating President Trump's exit strategy from the Iran war. Despite dismissing concerns about the strait, Trump argued that the US produces enough oil to sustain itself and other countries dependent on Middle Eastern oil should be responsible for easing the passage of oil tankers. However, oil is a globally traded commodity, meaning the US will not be immune to higher prices if Iran controls the 20 percent of the global supply that moves through the narrow strait off its shore. Iran appears to recognize this leverage, planning to implement a "toll booth" system that would price ships safe passage through the Strait. After Trump's remarks, oil prices jumped, which analysts attributed to dashed hopes that the president would outline a way out of the conflict. In the U.S., polls show the Iran conflict is unpopular and the surge in prices at the pump is likely not helping the situation.
