No Sonar Zone

I just read this article on CNN.com. It says that a judge has said the Navy cannot have an exemption from a law banning the use of sonar.

In 1941 the Army could not get a radar to the idea site on Oahu because it was a protected national park.

The similarity is noteworthy though 1) Placing the radar in that location would probably NOT have prevented the Pearl Harbor attack, and 2) a 12 nautical mile zone does not seem all that big a problem given the size of the Pacific. Unless of course, that particular area is special somehow from a training point of view.
