Stephen M. Walt in Foreign Policy:
The most obvious example of magical thinking in contemporary policy discourse, of course, is the myth of a “better deal” with Iran. Despite abundant evidence to the contrary, opponents of the JCPOA keep insisting additional sanctions, more threats to use force, another round of Stuxnet, or if necessary, dropping a few bombs, would have convinced Iran to run up the white flag and give the United States everything it ever demanded for the past 15 years. The latest example of such dubious reasoning is the New York Times’s David Brooks, who thinks an agreement where Iran makes most of the concessions is a Vietnam-style defeat for the United States and imagines that tougher U.S. negotiators (or maybe war) would have produced a clear and decisive victory.
Never mind that while the United States ramped up sanctions, Iran went from zero centrifuges to 19,000. Never mind that there was no international support for harsher sanctions and that unilateral U.S. sanctions wouldn’t increase the pressure in any meaningful way. Never mind that attacking Iran with military force would not end its nuclear program and only increase Iran’s interest in having an actual weapon. Never mind that the deal blocks every path to a bomb for at least a decade. And never mind that the myth of a “better deal” ignores Diplomacy 101: To get any sort of lasting agreement, it has to provide something for all of the parties.
