A cerebral Marine general who commanded all NATO forces in Afghanistan and later shaped the fight against the Islamic State.
John R. Allen's military career was defined by intellectual rigor and strategic command in the most complex warzones of the 21st century. A Marine Corps officer with a master's degree in national security, he was known as a soldier-scholar long before his promotion to four-star rank. His defining moment came in 2011, when he took command of the International Security Assistance Force in Afghanistan, tasked with managing the drawdown of U.S. troops and transitioning security to Afghan forces. After retiring, he re-entered public service as President Obama's special envoy to build the global coalition against ISIL, leveraging his diplomatic skill to unite dozens of nations. In later years, he has turned his focus to the future of conflict, writing extensively on artificial intelligence and hybrid warfare.

John was born in 1953, placing them squarely in the Baby Boomers. The events that shaped this generation — postwar prosperity, civil rights, Vietnam, and the counterculture — shaped the world they entered and the choices available to them.
