Yes, argues Matthew Kroenig; what’s more, it can be done without starting a war:
The first step to unwinding the Iran nuclear deal in a responsible manner is to establish a clear objective. That objective cannot be merely to punish Iran. The goal must be to reach a better deal, one that actually prevents Iran from building nuclear weapons. . . .
[O]n day one of his or her term, the new president can reinstate by executive order any sanctions that were suspended by the Obama administration. He or she can also put an immediate halt to the unfreezing of any still-frozen Iranian assets. Finally, he or she can cease the use of executive waiver authority, in order effectively to reinstate past congressional sanctions on Iran.
The next and most difficult step will be working with allies and partners to reinstate international and multilateral sanctions against Iran.
