Nuclear ProliferationLesson – Disarmament
Objectives Review goals of NPT treaty. Compare different types of weapons. Identify key treaties regulating
nuclear arsenals .
Warm Up
What are the goals of the NPT?
• Non-Proliferation• Disarmament• Fair Access for
Peaceful Use
http://www.hulu.com/watch/165125/movie-trailers-countdown-to-zero---exclusive-clip---proliferation
Peaceful Uses Nuclear Energy Controlled nuclear reactions
• Heat Steam Electricity (19% in US)
Nuclear power plants• Atomic energy
Radioactive Isotopes (Medicine, Agriculture, Industry)
Nuclear Regulatory Com Dept of Energy
Regulate use nuclear materials
Weapons Delivery Missiles deliver
conventional or nuclear warheads
Ballistic Missiles – enter atmosphere
Cruise Missiles – fly closer to ground
Tactical – short range missiles
Strategic – longer range missiles
IRBM • Tactical ~2,500 mile target• “Pershing Missiles”
SLBM• Strategic • “Poseidon / Trident”
ICBM• Strategic 20K mph, targets 9K
miles away• “Minutemen / MX”• US fixed site, USSR mobile
launchers ABM
• Destroy offensive missiles in space… ABM defense systems

Disarmament Negotiations US & Russia
possess ~95% total global arsenal.
Since 1963 have worked to stop proliferation & reduce arsenals (most of the time!)
Disarmament Negotiation LTBT (1963):
• US & Russia ban nuclear tests in atmosphere, underH20, & space…CTBT (1996 - …) banned tests in all environments (↓ground)
NPT (1968) : Nuclear Non-Proliferation Treaty
SALT I (1972):• ABM Treaty – Limit ABM systems, Pledge to not build ABM defense
systems (US withdrew to pursue NMD under GW Bush)• Interim Agreement – Froze # of strategic offensive weapons at
current levels
SALT II (1979):• Reduce strategic forces to 2,250 each ICBM/SLBM/ASBM• Limits # of warheads & weight per missile• Banned new strategic missile dvpt
Disarmament Negotiation INF TREATY (1987):
• Abolish all intermediate nuclear & conventional missiles (300-3400 m)…remove from E/W Euro
START I (1991):• Reduced # of strategic nuclear warheads from 10K per side
to 6K• ICBM’s to 1,600 per side/SLBM to 880 per side
START II (1993)• Reduce # of long-range missiles and nuclear warheads from
6K per side to 3,500K US/3K Rus.• Banned multiple warheads in strategic missiles• US reduce # of warheads on SLBM
Disarmament Negotiation SORT (2002)-
• US & Russia limit # of nuclear warheads 1700–2200 operationally deployed warheads each
• Provision aimed at preventing spread of WMD’s (material/tech) to terrorists.
New START (2010):• Reduce # of nuclear warheads to 1,500• Limit # of ICBM/SLBM missiles & launchers
and heavy bombershttp://www.washingtonpost.com/wp-dyn/content/article/2010/03/26/AR2010032601943.html
New START (2010)
Values Line Directions Take a few minutes to evaluate your
opinion on nuclear weapons… (survey)
Strongly Agree – 2 steps forward Agree – 1 step forward Undecided – Stay on the line Oppose – 1 step back Strongly Oppose – 2 steps back
Obama & Arms Reduction Nuclear Posture Review (NPR)
• http://www.youtube.com/watch?v=QKSn1SXjj2s
• Prevent nuclear terrorism & proliferation and reduce the role of nuclear weapons in our national security strategy, while sustaining a safe, secure & effective nuclear deterrent.
• Reading Activity “Nuclear Weapons Goals & Obstacles”
Moving Toward Zero
http://www.hulu.com/watch/148962/movie-trailers-countdown-to-zero---trailer#continuous_play=on
Homework: Wiki Post What should our nuclear weapons policy
look like?• Should we keep nuclear weapons as an essential
part of our security strategy? Modernize weapons, stockpiles, and a NMD.
• Should we rely on the current system of arms control and lead the international effort to strengthen treaties and minimize existing arsenals?
• Should we move toward nuclear zero and eliminate all nuclear weapons and defense systems now?
Closure
Identify and describe the goals of three of the disarmament negotiations discussed today.
