Butler Fellow for Military Affairs at the Libertarian Institute and host of Chasing Ghosts: An Irregular Warfare Podcast, where he critically examines U.S. military interventions and irregular conflict through a libertarian lens. A retired U.S. military officer with nearly 25 years of service, Buppert draws on his experiences in various global conflict zones to challenge conventional defense narratives and advocate for non-interventionist policies.
