Summary
John Mearsheimer reflects on how his military service during the Vietnam War shaped his offensive realist views. He argues the conflict revealed nationalism as a far more potent force than communism, debunking the domino theory and explaining why foreign interventions often fail. Mearsheimer also highlights the inherent limits of military power, noting that even superior forces cannot easily achieve social engineering or defeat determined nationalist movements. These lessons underpin his opposition to the invasions of Iraq and Afghanistan.
