Pentagon's plans to deploy an expensive space defense systen, similar to Reagan's SDI (Strategic Defense Initiative) or 'Star Wars' shield, are likely to be thwarted.
Prominent physicists and engineers claim that the 'Son of Star Wars' can easily be made ineffective if an incoming hostile missile consists of hundreds of bomblets each carrying biological or chemical material. The intercepting anti-missile would be unable to destroy all the bomblets, many of which would successfully hit their target. The enemy could also cool the missile's warhead with liquid nitrogen, so deceiving the defending missile's heat-seeking sensors. Or the attacker could confuse the system by enveloping the warhead in a special balloon and releasing decoy balloons.
Possible aggressors to the US or Britain could be North Korea, Libya or Iraq.
