Joseph Nye
Joseph Nye introduced the concept of "soft power" in the late 1980s. For Nye, power is the ability to influence the behavior of others to get the outcomes you want. There are several ways one can achieve this: you can coerce them with threats; you can induce them with payments; or you can attract and co-opt them to want what you want. This soft power – getting others to want the outcomes you want – co-opts people rather than coerces them.
