Micah Zenko, a senior fellow with the Council on Foreign Relations, delivered a lecture to cadets on how to “red team” in order to know one’s enemies and achieve victory on the battlefield. He says it is difficult for big organizations like the U.S. Army to know its blind spots and weaknesses. He divides the practice into three sub-categories: simulations, vulnerability probes, and alternative analyses. Taking questions from the audience, Zenko describes how the NYPD has employed red teaming and what lessons the Paris police department could have learned to avoid terrorist attacks like the recent ones carried out by the Islamic State.
