1 GO131: International Relations Professor Walter Hatch Colby College Nuclear Deterrence

2 Why the Dog Didn’t Bite (and the Cold War Stayed Cold) Balance of power? Or “balance of terror?”

3 A Puzzle for Realists Classical realism: Superpower Behavior Ideological moderation Fear of escalation Neo-realism: Structure of the System The stability of bipolarity Communication to overcome PD

4 Balance of Terror

17 North Korea Near war in ’94 over plutonium production Left NPT in ‘03 over uranium enrichment 6-8 nukes Diplomatic breakthrough?

18 Iran Signed NPT But enriching uranium For civilian or military purposes? Israel should be “wiped off the map…”

19 India’s Special Status 100 nukes? US cooperation Why not Pakistan?

20 Proliferation for Profit Pakistan –> Iran, Libya, North Korea China –> Iran Dr. A. Q. Khan

21 Testing CTBT (1996) Won’t take effect until signed and ratified by 44 states India and Pakistan refused to sign; conducted their own tests in late 1990s An attempt to divide world into “nuclear haves” and “nuclear have-nots?” U.S. Senate voted in 1999 against ratification Bush administration opposes it
