Lasswell Prize, Society of Policy Scientists.[4][5]

In 2017, Horowitz received the Karl Deutsch Award from the International Studies Association. This award is given annually to an individual under the age of 40 who is judged to have made the most significant contribution to the study of international relations and peace research.
