We can define “red lines” as acts, activities, or situations that if carried out or reached mandate actions to redress the situation. The purpose of drawing these lines is twofold: to deter these said acts or activities, and to judge that the situation is serious enough to warrant reactions. Red lines, virtual or real, have been drawn in the past as part of strategies to deal with the Iranian nuclear issue. These lines were defined and later crossed without any action taken – other than verbal.
