The last word I heard was that accuracy had actually improved, because the
US military forces in the Gulf are making extensive use of commercial
Navstar receivers, while the Iraqis have little or no Navstar equipment,
so the public-access code is being kept as undegraded as possible.

Why bother?  There is nothing secret about any of this.  There is nothing
to be gained, and a fair bit to be lost, by keeping the public in ignorance
of things Saddam already knows.
