What Are Iran’s Nuclear and Missile Capabilities?

Jonathan Masters and Will Merrow

Introduction

Many foreign policy experts warn that if Iran were to acquire nuclear weapons, it would be broadly destabilizing for the Middle East and nearby regions. A first-order concern is that Iran’s possession of nuclear weapons would pose a major, perhaps existential threat to Israel, its longtime foe. Other foreign policy experts say Iran would be assuring its own demise if it were to launch a nuclear strike on Israel, a close U.S. defense partner and possessor of its own nuclear weapons arsenal, which is undeclared. Either way, there would be a dangerous potential for miscalculation that could result in a nuclear exchange, analysts say.
Does Iran have a nuclear weapon?

Iran does not yet have a nuclear weapon, but it has a long history of engaging in secret nuclear weapons research in violation of its international commitments. Western analysts say the country has the knowledge and infrastructure to produce a nuclear weapon in fairly short order should its leaders decide to do so.

The United States, Israel, and other Middle Eastern partners regard Iran as a primary threat to their interests in the region, and view its potential acquisition of nuclear weapons as a game-changing scenario to be steadfastly prevented—by force if necessary.
