You are absolutely correct that there are many other terrorist leaders that will need to be removed from power.
The Coalition is merely putting a face on the first phase of this battle. Since bin Laden takes pride in praising these murderous attacks it only seems just that he and his extremists get our highest attention. After he either gives up or leaves this earth, then we will focus on other terrorist networks. It is a world wide effort to clean up these demons and give peace a chance. They want a Holy War of terror, the rest of the world wants world peace. Who do you think is going to win, the 10% or the 90%?
P.S. Did you hear that the Palestinians are denouncing bin Laden and that their police broke up some demonstrations? I heard it on CNN about 15 minutes ago but I'm not sure I heard it right. I can hardly believe it.
