If peace is to be achieved, diplomatic effort is as important as sanctions

TODAY, the United Nations Security Council has more sanctions regimes in place than at any time in its history. During the 1990s, the maximum was eight; in the 2000s, the peak rose to 12; now it stands at 16. And these totals do not include sanctions imposed by the European Union and the United States. Judging by this escalation, one might conclude that sanctions have proved a remarkably effective tool in promoting international peace and security. Unfortunately, that is far from being the case.
In fact, academic studies suggest that sanctions have had limited success. Thomas Biersteker of the Graduate Institute in Geneva estimates that sanctions are effective only about 20% of the time.
