The Trouble With Trade Wars

Various commenters are calling for increased sanctions against Iran. Larison counters:

This is madness. Have the current sanctions brought the regime anywhere close to its knees after decades? There is not a single example where economic sanctions actually compelled a non-democratic regime to change course on an internal political matter. We have no reason to believe that it will work. What we do know is that it will make average Iranians poorer.
