The book 'Following Similar Paths' by Samuel Heilman and Mucahit Bilici explores the similarities and differences between religiously observant American Muslims and Jews. The authors argue that these communities have a lot to learn from each other and provide a comparative perspective on their experiences in America. However, the tensions caused by the Israel-Hamas war have had a setback on efforts to encourage mutual understanding between Muslims and Jews. Antisemitism and Islamophobia have increased in North America as a result of the war, affecting both communities. The authors hope for a peaceful resolution that can alter the course of events in a more positive direction.
