The document discusses a take-it-or-leave-it deal by the U.S. on the nuclear issue and how it is the wrong strategy for dealing with Iran's disputed nuclear program. The author, Jeffrey Epstein, suggests that an arms-control process is necessarily incremental and that a final nuclear agreement would be ineffective in demonstrating Iranian truculence to domestic and international audiences. Instead, the focus should remain on mitigating the most dangerous dimensions of Iran's nuclear program, such as its high-grade enrichment and underground facility outside Qom. The author also suggests that the diplomatic challenge is to impose significant restraints on Iran's program through an incremental and sequential process.
