After former President Trump’s recent digs at NATO, officials at a global security conference in Munich over the weekend weighed what European countries would do if Trump were re-elected and abandoned the United States’ treaty commitments. On the show today, Kathleen McInnis, senior fellow at the Center for Strategic and International Studies, discusses the history and future of NATO and why it matters to the global economy. We’ll also share our takeaways from Fani Willis’ testimony. Plus, a former NASA astronaut was wrong about what we (earthlings) gain from going to space.
