Should Iran’s clerical regime acquire nuclear weapons, as is its evident aim, it would be able to foment mischief in its region or beyond without fear of regime-threatening retaliation – other than from another nuclear power. In a suicidal mood, it could well lash out at Israel, Europe, or at American forces in the region. Inevitably, regional powers such as Saudi Arabia will seek nuclear weapons of their own so that they will not have to rely on others to secure their survival.
