“Robert Kagan is a neoconservative writer and historian based at the Brookings Institution. A longtime proponent of an aggressive, interventionist U.S. foreign policy, Kagan has played an influential role in shaping the neoconservative agenda for more than two decades. Kagan is also one of a host of neoconservatives to have vocally criticzed Donald Trump, whom Kagan has called “the most successful demagogue-charlatan in the history of U.S. politics.”
Kagan was a cofounder of the Project for the New American Century (PNAC), a now defunct pressure group that helped build Beltway support for the U.S. invasion of Iraq throughout the 1990s and early 2000s. In the early years of the Obama administration, he reprised this role as a cofounder of the Foreign Policy Initiative, a PNAC successor group.”
