Just the threat of sanctions can be an effective coercive tool.  Most diplomatic negotiations occur behind closed doors, and it has been hypothesized that if sanctions are going to be effective it is the threat of the sanctions that forces the country to concede, not the sanctions themselves1. That said, if sanctions were never followed through, the threat would be meaningless. The use of sanctions builds up the fear of sanction. This fear can bend countries towards the will of the sanctioning nation. To maintain the threat of sanctions as a viable negotiating tool, sanctions need to be implemented on occasion to prevent sanctions from becoming an empty, meaningless threat. 1 Colvin, Jake and Cox, Simon (2007), "Are Economic Sanctions Good Foreign Policy?", Council on Foreign Relations, [Accessed June 10, 2011].
