President Trump’s strikes on Iran have reignited the American foreign policy debate. For decades, libertarians like myself have hammered the mistakes of the War on Terror, especially in Iraq. Ron Paul’s 2007 presidential debate performance laid out the blowback risks of interventionism, highlighting a specific story of American meddling in Iran—one I believed until very recently. President Trump is resetting long-held assumptions about regime change and endless war, forcing me to rethink the complexity of geopolitics. Caught between conspiracy theories of Israeli control and premature declarations of “mission accomplished,” Americans must decide for themselves what to think in these tumultuous times.
