The Navy today shot down an obsolete spy satellite. The nominal reason was to prevent it from hitting anyone and making a mess when it hit. In fact the purpose was to demonstrate the Navy's capability to shoot down satellites, and by extension, missiles. The Chinese have already shot down one of their own weather satellites for the same reason. Absurdly the United States protested the Chinese satellite-whacking as provocative and complained that it littered space with debris. Lehrer had a military camp follower in a suit and a pious schmuck from MIT to debate the shooting down.
The pimp in the suit pretended not to know that the purpose of the shoot was to demonstrate the capability of doing it. The pious schmuck from MIT (he even had a beard) belabored that the purpose of the shot was not actually to shoot the satellite down.
The MIT professor went on to object to the shot on the ground that the Russians and Chinese wouldn't like it. I guffawed. The purpose of the exercise was for the Russians and Chinese not to like it.
