# Summary

The assertion that Washington and Tehran need not remain permanent adversaries opens a debate about long-term U.S.-Iran relations that transcends the current administration's approach. The relationship between the United States and Iran has oscillated between hostility and brief windows of diplomatic engagement over four decades, most notably with the 2015 Joint Comprehensive Plan of Action negotiated by the Obama administration.

The Trump administration withdrew from the JCPOA in 2018, reinstating sanctions and eliminating the framework that had constrained Iran's nuclear program. The Biden administration has expressed willingness to rejoin the agreement, but negotiations have stalled repeatedly over terms of re-entry and Iranian compliance verification.

This framing suggests that despite decades of tension rooted in the 1979 Islamic Revolution, the Iranian hostage crisis, proxy conflicts throughout the Middle East, and competing regional interests, fundamental pathways to reconciliation remain possible. Both nations face mutual benefits from de-escalation. Iran seeks relief from crippling economic sanctions. The United States seeks assurances regarding Iran's nuclear ambitions and regional military activities.

However, structural obstacles persist. Iran's government views the U.S. as an existential threat and maintains influence through militias and proxies in Iraq, Syria, Lebanon, and Yemen. The American security establishment remains deeply skeptical of Iranian intentions. Congress, with bipartisan skepticism toward Iran, constrains executive flexibility in negotiations.

Practical reconciliation would require both governments to accept incremental trust-building rather than comprehensive resolution. Renewed nuclear diplomacy, confidence-building measures on regional conflicts, and potential prisoner exchanges represent feasible starting points. Success depends on whether either administration prioritizes diplomatic investment over hardline constituencies.

The proposition that enmity need not be permanent challenges deterministic views of international relations while acknowledging that transformation requires political will from both capitals and sustained domestic support for diplomatic initiatives that
