While the JCPOA has required Iran to do major program-retrenching steps such as gutting nuclear reactors and enrichment cascades, it required nothing from the United States other than the lifting of sanctions whose very purpose was to induce Iran to take the kind of bomb-precluding measures that the JCPOA incorporates. Lifting those sanctions was a net plus, not a minus, for the United States in terms of not only nuclear nonproliferation but also trade, investment, and other economic considerations. Herein lies a legitimate reason, by the way (in addition to the anticipated handling of the issue by Republicans in the Senate) for not making the JCPOA a treaty. The agreement imposed no costs or constraints on Americans, as treaties can do in becoming part of the law of the land. Even without sanctions, no company was required to do any business with Iran if it didn’t want to.
