Despite the fact that many politicians support the idea of using sanctions as an instrument of politics, they reckon sanctions are more human way of conducting foreign policy than war. But again the experience of the implementation of economic sanctions against Iraq. According to UNICEF, economic sanctions against Iraq has led to an increase in mortality among children under 5 years of age more than doubled, and in total caused the death of more than 500,000 children between 1991 and 1998 from malnutrition, lack of medicine, clean water and etc.( Pigler , J. Even Before the 200 War, We Were Attacking Iraqi Civilians with our Inhumane Economic Sanctions. Statesman, 4.11.2004) 

The conception of sanctions is the idea of cause suffering to the people (citizens) and then they can influenced their government. The citizens of the country where sanctions were applied are used as a means of achieving the goals of the state, declaring sanctions.

Therefore, sanctions are not an effective means of resolving international conflicts neither in economic nor in political concepts. Using sanctions can be explained by the desire of the head of the state to raise its credibility, achieve international recognition of the state in the international arena, to get worse the political situation and destabilize the state affected by sanctions. The main purpose of sanctions to make a state to change the behavior but likely it won't be achieved.
