Kagan graduated from Hamden High School before he earned a B.A. in Soviet and East European studies and a Ph.D. in Russian and Soviet military history, both from Yale University. He worked as an Assistant professor of military history at West Point from 1995 to 2001 and as an associate professor of military history from 2001 to 2005. The courses that he taught at West Point included the history of military art, grand strategy, revolutionary warfare, and diplomatic history.
He and his father, Donald Kagan, who was a professor at Yale and a fellow at the Hudson Institute, both authored While America Sleeps: Self-Delusion, Military Weakness, and the Threat to Peace Today (2000). The book argued in favor of a large increase in military spending and warned of future threats, including from a potential revival of Iraq's weapons of mass destruction program. Frederick along with his brother Robert Kagan, who is a member of the Aspen Strategy Group, and their father, Donald, were all signatories to the Project for the New American Century manifesto, Rebuilding America's Defenses (2000).
Kagan authored the "real Iraq Study Group" report as the AEI's rival to the ISG report of James Baker and Lee H. Hamilton in December 2006. The AEI report, titled Choosing Victory: A Plan for Success in Iraq, was released on January 5, 2007, and Kagan was said to have won over the ear of President George W. Bush, strongly influencing his subsequent "surge" plan for changing the course of the Iraq War. Along with retired General Jack Keane, retired Colonel Joel Armstrong, and retired Major Daniel Dwyer, Kagan is credited as one of the "intellectual architects" of the surge plan. According to Foreign Policy magazine, Kagan's essay "We're Not the Soviets in Afghanistan" influenced the strategic thinking of Secretary of Defense Robert Gates, which reportedly influenced Gates' decision to support sending 30,000 additional troops to Afghanistan.
Remarking on the surge in 2015, Kagan said while the AEI group convened that "it never occurred to me or anybody that was involved in this that we were going to affect policy. It was simply 'Maybe we can put some concrete numbers on the table, some concrete enemy on a map, some concrete units on a grid, and force other people who want to have this discussion to wrestle with the specifics of the problem.'"
In 2010, U.S. Army General David H. Petraeus, who was appointed by President Barack Obama to head international forces in Afghanistan, hired Kagan as one of two experts on fighting corruption. An article in the Washington Post on 19 December 2012 discussed the relationship that the Kagans had with General Petraeus and, to a much lesser extent, with his successor in July 2011, General John R. Allen. It discussed various visits made by the Kagans from mid-2010 including their having been given access to the Combined Joint Intelligence Operations Center in Petraeus' headquarters. It commented on and raised questions about their sponsorship by Defense contractors through the American Enterprise Institute. It also detailed how the Kagans had become involved in Iraq in 2007 under an initiative by General Stanley A. McChrystal, who was their first introduction to Afghanistan in 2010.
