Foreign Policy Initiative
The Foreign Policy Initiative (FPI) is a neoconservative think tank begun in 2009 by William Kristol and Robert Kagan, two founders of the Project for the New American Century. FPI is, according to its website, "that promotes continued U.S. engagement -- diplomatic, economic, and military -- in the world and rejection of policies that would lead us down the path to isolationism; robust support for America’s democratic allies and opposition to rogue regimes that threaten American interests; the human rights of those oppressed by their governments, and U.S. leadership in working to spread political and economic freedom; a strong military with the defense budget needed to ensure that America is ready to confront the threats of the 21st century; and, an international economic engagement as a key element of U.S. foreign policy in this time of great economic dislocation." 
Kagan worked at the State Department Bureau of Inter-American Affairs (85-88) and was the principal speech writer for Secretary of State George P. Shultz (84-85). Prior to that, he was foreign policy advisor to Jack Kemp. His name is associated with the Carnegie Endowment for International Peace.
Kagan, who has written for the New Republic, Policy Review, the Washington Post, and the Weekly Standard, now lives in Brussels, Belgium, with his family.
Ahead of the lecture Kagan told ABC Radio that if diplomatic measures failed to deter Iran developing its nuclear capability the US may resort to military measures. "Again, one would hope, and maybe there are signs that diplomatic efforts will succeed, but anyone who thinks that it's inconceivable that there could be a military option in Iran sometime down the road I think is making a mistake," he said.
