The leaders of Australia, India, Japan, and the United States meet virtually this morning for a summit, as the Biden administration seeks to make good on its commitment to multilateralism, as well as sending China a signal of unity among the regional powers.

Lt. Gen. H. R. McMaster, US Army, ret., the former national security advisor and the Fouad and Michelle Ajami Senior Fellow at the Hoover Institution discusses his latest book, Battlegrounds: The Fight to Defend the Free World, a re-examination of the most critical foreign policy and national security challenges that face the United States, and an urgent call to compete to preserve America’s standing and security.

Call Sign Chaos is Jim Mattis’s memoir of his lifelong journey from marine recruit to four-star general and secretary of defense. It’s also the story of his quest to learn from every experience and pass on those lessons, so that future generations can plan better, lead better, and do and be better, thus creating a safer and more successful United States and world.
