Amid nationwide unrest in Iran, U.S. President Donald Trump announced on January 12 an immediate 25 percent tariff on any country doing business with Iran as part of a broader pressure campaign that could include military options. International relations expert James Dorsey warns that Venezuela could reshape the global oil market if Washington gains control. If Iran re-enters the market under a pro-U.S. regime, America's influence would skyrocket. But Trump's push for a $50 oil price clashes with Gulf state budgets and threatens U.S. shale producers. Is this a geopolitical pivot or a policy contradiction?
