To explain the political deficiencies of sanctions against Iran after the victory of the Islamic Revolution, it is always debated that the experience of Iran in addressing the challenge of the sanctions resulted in self-sufficiency and decrease of vulnerabilities against economic restrictions. The new sanctions failed on the same ground.
The present article aims to examine this process. Based on economic statistics, the author emphasizes that Iran’s economic vulnerabilities in three areas of dependency to foreign investment in energy sector, dependency to oil exports and imports of oil products including gasoline not only diminished but it turned to be a point of strength if the current circumstance compared with previous years. It is also explained that the nature of sanctions before and after 2006 are quite different evolving from symbolic sanctions to more punishing and deterrent one. This process for itself is a clear indication that the sanction policy is defective in nature.
