Jonathan Horowitz is Legal Adviser (Deputy Head of the Legal Department) at the International Committee of the Red Cross (ICRC) Regional Delegation for the United States and Canada, based in Washington, DC. He is widely recognized for his expertise in international humanitarian law (IHL), human rights law, and the legal governance of armed conflict.

Prior to joining ICRC, Horowitz worked with organizations such as the Open Society Justice Initiative, UN human rights bodies, and legal defense teams—focusing on detainee treatment, human rights abuses, and fact-finding methodologies in conflict zones (Afghanistan, Sudan, Pakistan, and beyond).

At ICRC, he has been a leading voice on the legal implications of new technologies in war, urban warfare, and civilian-harm mitigation — including authorship of influential work such as “One Click from Conflict,” which explores legal considerations for digital-technology companies operating in conflict zones.

His contributions help bridge the gap between evolving military, technological, and humanitarian realities — shaping how international law adapts to challenges like AI, cyber warfare, and civilian protection under the law of armed conflict.
