  Remember, there is only one (1) frequency spectrum in the world and
  everybody - military, civilian, U.S., Iraqi -  uses it.

  And modern technology *could* allow the jamming of the entire spectrum.
  But then, you'd be jamming all the friendly frequencies, too - and 
  interfering with your own operations.  So, obviously, you protect the
  frequencies that you have to use.  

  Also, we're not going to jam any key frequencies that are providing us
  with critical information.  There's a tradeoff - do we destroy it - 
  or monitor it?

  Also, it is the receiver of the signal that is the target for jamming -
  not the transmitter.  And then there are anti-jam methods - like 
  increasing power to 'burn' through the jamming - frequency-hopping
  transmitters etc.   

  It's all very complex - I probably oversimplified it - but I'd rather not 
  get into *details* of radio electronic combat.

        Whats the best anti-jammer?    A 155mm artillery round!
