Business negotiators sometimes face the difficult question of whether to negotiate with someone they believe to be immoral, untrustworthy, or otherwise undesirable as a negotiating partner. In his book Bargaining with the Devil: When to Negotiate, When to Fight (Simon & Schuster, 2011), Program on Negotiation chair Robert Mnookin offers advice on the complex question of whether to negotiate with an unsavory party. The question becomes all the more complex when we would be negotiating not on our own behalf, but representing someone else. Turning to the realm of international negotiations, that issue came to the forefront upon the killing of journalist James Foley by the terrorist group the Islamic State in Iraq and Syria (ISIS) on August 19. In interviews with the New York Times, members of Foley’s family described the confusion and stress they faced when they found themselves virtually alone in trying to negotiate his release. About a year after Foley’s capture in Syria in November 2012, ISIS sent an email to his brother, Michael Foley, that revealed the group wanted money for Foley’s release. A follow-up email demanded about $130 million in ransom and the release of Muslim prisoners from the United States.
