The U.S. military is to a certain extent a microcosm of the population it serves. While this ensures that the military includes the best characteristics of society, it also means that the military must contend with societal challenges as well. Political polarization among the citizens of the United States is higher than it has been in decades, and that has implications for a representative military. Michael Robinson is in the studio to discuss his study of the phenomenon and the potential politicization of the military ranks. He joins host Carrie Lee for a conversation about his book, Dangerous Instrument: Political Polarization and U.S. Civil-Military Relations. This is the second episode in our special series supporting the U.S. Army War College’s Civil-Military Relations Center.
