Stefan A. Halper (born 4 June 1944, as published on the IWP faculty line) is an American foreign-policy scholar. The same bio lists White House service in the 1970s, a Deputy Assistant Secretary of State title in the Reagan years, and a Cambridge American Studies appointment. Later reporting and declassified FBI handling files identify him as a confidential human source used in Crossfire Hurricane. This page is identity. The episodes live in the posts. This is not the biography he would write.
