Iranian weaponization could undermine U.S. credibility and the legitimacy of the international nonproliferation regime.6 Iran’s development of nuclear weapons could undermine the reputation of the United States, and lead allies to question its commitment to their defense. This is particularly the case given the United States’ repeated statements that it will not accept an Iranian nuclear arsenal. Because Iran is a signatory of the Nuclear Nonproliferation Treaty (NPT), its development of weapons could undermine the legitimacy of the treaty and compli- cate multilateral nonproliferation efforts.
The nonproliferation regime is under a lot of stress after 40+ years of attempting to prevent a wave of nuclear proliferation. With the international community unable to prevent North Korea from successfully obtaining a nuclear weapon, some experts are concerned that if Iran goes nuclear, it would push the regime over the tipping point.
