    Getting 'Left-of-Launch' in the Counter-Drone Fight

    The democratization of drone technology means that adversaries are now able to conduct attacks with near impunity. The Houthis' recent drone attacks in the Red Sea show that America's current approach to countering them is not working. A holistic, offensive strategy is needed.

    UFOs Are Not the Only Potential Threat in American Skies

    How can the United States best monitor its millions of square miles of domestic airspace for unidentified anomalous phenomena—what were once called UFOs—or anything else? Public reporting could help officials identify potential threats—but it'd help if the sightings being reported were actually unknown aerial phenomena and not U.S. military aircraft.
