16. Mark Milley
General Mark Milley, as Chairman of the Joint Chiefs of Staff, has been a central figure during some of the most politically charged moments in recent U.S. history. Navigating the Trump and Biden administrations, Milley faced both praise for upholding the principle of military nonpartisanship and criticism for his actions during events such as the January 6 Capitol attack. His tenure has sparked vigorous debate on the role of military leaders in preserving democratic norms amid political upheaval (via NPR).
