MILITARY RESEARCH:
Missile Defense Rides Again
James Glanz
A new push to erect a ballistic missile shield is technologically more plausible than the 1980s "Star Wars" program, shunning ambitious technologies in favor of existing know-how. To skeptics, however, the effort remains futile and dangerous. They argue that any system deployed nationally could alarm adversaries that the United States could launch a first strike and then parry a counterattack, and that no matter how good, the system would be vulnerable to crude countermeasures such as decoys.
