Commander of U.S. Central Command Gen. James Mattis said Tuesday that "at least one other nation" has told him "at the leadership level" they will seek nuclear weapons if Iran goes nuclear:
SEN. LINDSEY GRAHAM (R., S.C.): If the Iranians develop a nuclear capability, how certain are you that other nations in the region would acquire an equal capability?
MATTIS: At least one other nation has told me they would do that, at a leadership level, they have assured me they would not stay without a nuclear weapon if Iran armed.
GRAHAM: Was that a Sunni-Arab state?
MATTIS: Yes, sir.
GRAHAM: So the likelihood of Sunni-Arab states acquiring nuclear capability to counter the Shia Persians is great, would you not agree with that?
MATTIS: I agree, and also other non-Sunni-Arab states in the general region.
The statements by Mattis contradict the findings of a recent report drafted by former Obama Pentagon official Colin Kahl and produced for the Center for New American Security. That report argues that Saudi Arabia–as well as other states–would be unlikely to develop nuclear weapons if Iran acquired nuclear weapons.
