Additional notes to students: THE PROBLEM PRESENTED IS HYPOTHETICAL AND INVENTED TO TEST YOUR ABILITY TO DO OBJECTIVE ANALYSIS NOT AS A PREDICTION OF WHAT WILL HAPPEN.

• You must accept the probabilities and the centrifuge information as given. Problem Introduction: Background:

On July 14, 2015 the E3/EU+31 (China, France, Germany, the Russian Federation, the United Kingdom and the United States, with the High Representative of the European Union for Foreign Affairs and Security Policy) and the Islamic Republic of Iran announced what they called a “historic Joint Comprehensive Plan of Action (JCPOA), which will ensure that Iran’s nuclear programme will be exclusively peaceful, and mark a fundamental shift in their approach to this issue.”2

                                                                                                                         1 Also referred to as the P-5+1 (US, UK, France, Russian Federation, China + Germany) and EU.

MS&E  193/293  –  HW2  –  Page  3    

In September 2015, the Obama administration stopped Congress from blocking the deal in spite of strong opposition from the Republican majorities. The deal is designed such that Iran must take actions to extend its breakout timeline – the time it will take to produce sufficient highly enriched uranium for one nuclear device (for the purpose of this exercise assumed to be 25 kg) – from the currently estimated 2 to 3 months to one year for at least the next decade. The Republic of Iran has committed to – among other provisions – reducing its installed centrifuges by 2/3, limiting its existing stockpile of low enriched uranium (LEU) from 10,000kg to 300kg, permitting regular IAEA access into nuclear facilities, and providing advanced notice of the construction of new facilities. In return, the United States and the other nations party to the agreement have agreed to roll back sanctions on Iran according to the schedule stipulated in the JCPOA. Failure on the part of the Republic of Iran to adhere to the agreement will result in immediate reinstatement, or “snap-back,” of sanctions.

As we enter October 2015, implementation of the plan begins according to the terms of the JCPOA in spite of persistent opposition in the U.S. Congress and in some quarters of Iran’s policy community.

The Hypothetical Problem:

The date is April 15, 2016. The U.S. Intelligence Community (IC) reports indications of a possible clandestine centrifuge site at one of Iran’s large military bases. Initial reports based on overhead imagery and human intelligence sources indicate the possibility of 30,000 centrifuges in a nondescript warehouses on the base. The Israeli IC has picked up similar indications, and Prime Minister Netanyahu has called upon President Obama to press for U.S. military action to destroy the warehouses. (For the purposes of your analysis, assume that the IC has confirmed with absolute certainty the existence of the covert centrifuge site. In reality, intelligence reduces uncertainty but does not eliminate it.)

President Obama convenes an emergency meeting of the National Security Council to decide what actions to take in light of this new intelligence. Secretary of Defense Ashton Carter presents Option A: Conduct a surgical military air strike to destroy the suspect facility. Secretary of State John Kerry presents two options: Option B: Convince the other parties of the JCPOA to impose snap-back sanctions to convince Iran to open the facility for inspection and roll back the potential clandestine centrifuge program. Option C: Take no action so as to allow the current JCPOA to proceed with scaling back Iran’s known centrifuge program.

*All events described beyond Oct. 7, 2015 are purely hypothetical. Although they have not actually transpired, you should assume that they have. For Option A: In the event of US airstrike, the suspected centrifuge facility will be successfully destroyed with probability of 0.90. If successful, Iran will rebuild the facility with same capacity in a different covert location, but construction may take over a year. Based on intelligence, it is estimated that there is a 0.1 probability that Iran will have a new facility operating with 30,000 P-1 equivalent centrifuges by April 15, 2017. If the strike is not successful, the covert facility will continue operating through April 15, 2017.

MS&E  193/293  –  HW2  –  Page  4    

If an air strike is conducted, regardless of whether or not it is successful, Iran will consider the JCPOA void and reactivate the full capacity of its Natanz and Fordow centrifuge facilities within the next year. For Option B: If the US takes no military action and pursues the diplomatic path with the P-5+1, there is a 0.4 probability that the P-5+1 will be convinced by the intelligence and snap-back the pre-JCPOA sanctions. If sanctions are snapped back in place, Iran will open the covert facility to inspection and give up its covert pursuit with probability of 0.8. If sanctions are snapped back in place, Iran will reactivate its Natanz and Fordow facilities with probability of 0.2. On the other hand, if sanctions are not snapped back in place, Iran will proceed with its covert facility with probability of 0.8. If sanctions are not snapped back in place, Iran will reactivate at full capacity its Natanz and Fordow facilities with probability of 0.6. For Option C: If the US takes no military action and decides to prioritize preserving the JCPOA for the time being, Iran will activate its covert facility within the next year with probability of 0.9. With no public mention of the covert facility, Iran will likely keep the JCPOA commitment to deactivate the Natanz and Fordow facilities to the levels and at the pace specified in the JCPOA (with a probability of 0.95). There is a probability of 0.05 that Iran will not comply and break out with its centrifuge facilities at Natanz and Fordow. For all options: Although the known centrifuge sophistication at Natanz and Fordow are different, for the purpose of this problem, you must assume that the two facilities will be reactivated together for a total capacity of 20,000 equivalent P-1 centrifuges. We would expect a covert facility to use advanced centrifuges that Iran has been developing, but for this analysis you must assume that the total capacity of the covert facility is 30,000 equivalent P-1 centrifuges. You are also not expected to consider the pace at which Iran has been converting its low enriched uranium per the JCPOA. For this problem President Obama will make his decision based on minimizing the expected number of P-1 equivalent centrifuges Iran has running on April 15, 2017. The Assignment:

President Obama asks his National Security Advisor (NSA) to analyze the three options and make a recommendation.

You are a senior security analyst.

• The NSA asks you to analyze the situation and prepare a two- to three-page executive summary in which you summarize your assessment of the situation, briefly analyze the options, present the pros and cons, and make a recommendation based on BOTH your quantitative and qualitative analysis.

• The NSA will use your executive summary to make a recommendation to President Obama.

• The NSA emphasizes that he wants an objective analysis, not your opinion.

MS&E  193/293  –  HW2  –  Page  5    

• The President is a risk-neutral (expected value) decision maker and seeks to minimize the total number of P-1 equivalent centrifuges operating in Iran on April 15, 2017.

• The intelligence services have provided probabilities for the three options (Table 1). You cannot question or change these.

• You must construct a decision tree to compare the alternatives. The decision tree will account for 50% of your grade for this assignment.

• You must consider qualitative factors in making your recommendation, including the unintended consequences of each of the alternatives.

• Your executive summary should briefly summarize the results of your quantitative analysis. You should spend no more than one half page summarizing your quantitative analysis; rather, let your quantitative analysis figures stand for themselves. The bulk of your executive summary should focus on your qualitative analysis.
