In 1979, she contributed alongside Jacques Soustelle, Lord Chalfont, Brian Crozier, Scoop Jackson, Jack Kemp, Richard Pipes, Norman Podhoretz and the then director of the CIA George H. W. Bush to the first of the two conferences on terrorism organised by Benjamin Netanyahu's Yonatan Netanyahu Anti-Terror Institute, which laid the intellectual groundwork for the War on Terror.

The Association Annie Kriegel, of which Emmanuel Le Roy Ladurie was the first president and Stéphane Courtois the secretary-general, is named in her honour.
