I've joined Bluesky (obviously). Good to be with you all. I'm a Legal Advisor at the ICRC's office in D.C., working on emerging tech, urban warfare, and partnered ops. I'm also at technconflict.substack.com. https://technconflict.substack.com13 Nov 2024 17:14 +0000at://did:plc:m4gbquebcco7ozd2svlnk42x/app.bsky.feed.post/3lattuwagke2qhttps://bsky.app/profile/jonathanhorowitz.bsky.social/post/3latt4frkkm2qIt was a pleasure speaking with @lawfare.bsky.social about how the laws of war address risks that arise when tech companies offer support to belligerents. A key point: These companies and governments need to talk about these risks with each other with the aim of avoiding harm to civilians.
