Episode description
John Allen is a retired four-star Marine Corps general who commanded 150,000 US and NATO troops in Afghanistan and built a 65-nation coalition as Special Presidential Envoy to the Global Coalition Against ISIS. After retiring from the military, he led the Brookings Institution as its president. He co-invented the term "hyperwar," holds five AI patents, and co-authored Turning Point: Policymaking in the Era of Artificial Intelligence. He currently serves as a strategic advisor to Microsoft.
In this episode of Summation, John and Auren discuss:
- Why Ukraine's battlefield is accelerating the autonomous weapons timeline faster than any defense department predicted
- The single assumption that doomed Afghanistan and why 2,500 troops could have changed everything
- What nobody is asking about the US operation in Iran
- How China's one-child military could be the most underappreciated deterrent against a Taiwan invasion
