It is well documented that economic sanctions on their own have not generally been effective in achieving their political aims, particularly when they are imposed against non-democratic regimes. Sanctions have their greatest impact in the short term, as their effects tend to be mitigated in the longer term by structural economic and political adjustments. Overall, effective sanctions have been short-lived, whilst ineffective ones have lasted a long time.
