1. Missile Defense (1) US Missile Defense in East Europe (2) Maneuvering Warheads as Countermeasures
(1) US Missile Defense in East Europe • Question: How capable the system is to intercept Russian missiles if it can intercept Iranian missiles; • Capability rather than intention; • Intercept range rather than killing probability
Interceptors • BPI（Boost phase Interceptor）: its range does not cover Iranian missiles flying to the US； • THAAD: its range does not cover Iranian missiles flying to the US； • GBI (Ground Based Interceptor): guided by radar; • KEI (Kinetic Energy Interceptor): guided by satellite & radar
KEI in EU & GBI in AlaskaIntercept Russian Missiles • KEI in EU intercepts Russian missile at 585s; • KEI in EU & GBI in Alaska form a layered defense; • GBI in EU contributes little
Conclusions • GBIs in EU, which cover Iranian missile, do not add new threat to Russia; • KEIs in EU pose new threats to Russia by adding a layer of defense; • US commitment of GBIs only in EU can help avoid security dilemma
2. Maneuvering Warheads as Countermeasures • Russia & China declared that maneuvering warheads help penetrate missile defense; • The research is to understand whether and how it works; • China case; • Ongoing work
Preliminary Results • Solid-fueled missile (DF-31) is not able to do this due to limited payload; • Liquid-fueled missile (DF-5) may or may not be able to do this; • Depends on the vulnerable time window
Vulnerable Time Window &Depressed Trajectory • Depressed trajectory shorter vulnerable time window less fuel for maneuvering.
Export Control • Impact of US export control on its trade with China; • Economic factors in export control: scale economy
US Export to China (M$) Cox Report Tian’anmen Sq Taiwan Str EP3 RMB devalued
How US Export Disturbed • Licensing contributes little; • Psychological burdens contributes a lot: • sanctions, • fear of accusation by ultranationalists
2. Economical Factors in Export Control Policy? • Economical factors drive the export control policies of all countries. • The US has had big markets in most areas, so it is not eager to expand its markets by lower export control standards. • Countries with small domestic markets and small fraction in international markets may be different.
A US Case • US nuclear industry has zero domestic market and small international market; so it needs to create new market. • US-Indian nuclear deal
