The United States has a clear interest in preventing such an Iranian capability. Iran has been a de-stabilizing force in the Middle East. As former Secretary of State Henry Kissinger wrote in the Washington Post last week: “Everything returns to the challenge of Iran. It trains, finances and equips Hezbollah, the state within a state in Lebanon. It finances and supports Moqtada al-Sadr’s militia, the state within a state in Iraq. It works on a nuclear weapons program which would drive nuclear proliferation out of control and provide a safety net for the systemic destruction of at least the regional order.”
