In this episode of Summation, John and Auren discuss:

    Why Ukraine's battlefield is accelerating the autonomous weapons timeline faster than any defense department predictedThe single assumption that doomed Afghanistan and why 2,500 troops could have changed everythingWhat 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
