Principle #11 - SANCTIONS NEVER WORK.
Example: Lybia never really suffered under sanction from the West, and Kaddafi didn't change his threatening ways until America in 2001 got tough on Terrorist states. The lesson is economic sanction never work unless the whole world community shuts out the bully state. As history has proved, some other bully country will trade or give aid to other trouble making bully states, thus rendering sanctions impotent.
