For over 250 years, the American military has tried to define what a man is supposed to be: tough, aggressive, and dominant. Those ideals have traveled beyond the battlefield, shaping schools, politics, pop culture, and expectations of boys and men. In journalist Jasper Craven's new book, God Forgives, Brothers Don't, he examines how military academies, ROTC programs, and other institutions have popularized that narrow model of masculinity, revealing a culture built around hierarchy, discipline, and service, but also marked by hazing, misogyny, racism, violence, and the suppression of vulnerability.
