In Iran, officials blame the sanctions for the economic crisis, while in the United States, officials blame the Iranian government. There is no denying that Iran’s economy has serious problems that have nothing to do with sanctions, but there is no doubt that the current crisis is the result of the sanctions. The same economy was able to expand by 18 percent in the two years that sanctions were partially lifted as a result of the 2015 nuclear deal. However, regime-change advocates in the United States who hope that sanctions will precipitate economic collapse will be disappointed. Economies do not collapse—they shrink. How far Iran’s economy will shrink and how Iran’s leaders and its people respond to the contraction are the real questions. Will the economy bottom out in 2019 or continue to slide for several more years?
