Well said Allen..
But I must mention that bombing for bombings sake != productive/useful.
It is very easy for Osama to hide in a nountain until the threats subside.
I just feel it obvious that a bombing has a high chance of missing the targets (they've prepared this for how long? surely they have hidden/removed anything of value by now), and more of a chance of hitting innocents.
The deaths of innocents will only strengthen the terrorist' resolve and perhaps add a few more angered by the US attacks.
