rotation? (Score 2, Interesting)

I remember reading a long time ago that a low-tech solution to laser-based missile defense was to have the warhead/missile/etc... rotate. In order for the laser to be effective, it would have to be hitting the same spot no?

PS - There was a good article in this past months Discover Magazine regarding the Missile Defense Initiative, and how low-tech solutions can beat most if not all of the US's tactics at this point.
