Afghanistan has earn merits enough to get hit. It's not they are related or not with this particular tragedy. I think this is the heart of the matter. I, in particular, thank the U.S. for taking this action. Taliban countries are terrorist countries. Ask their own people. I think PC times are over. Everyone has to know for certain that terrorism in any way will be accountable for retaliation. As fast and hard as possible.
If I see this as a first step and a change int the world's attitude with regards to terrorism (national, international, muslim, christian, whatever it is), it's quite OK with me.
