Mansoor Ijaz seems like a straight shooter to me. His words, quoted above, got my attention. If the attack is in the form of biological agents there is not much we as citizens can do. I believe it is justifiable because it is war and a matter of life and death for us as citizens.
Every time there is a threat I would like to see our government wage an unrelenting attack against al Queda strongholds like the major one on the Afghan-Pakistani border southeast of Khabul. In this case I would recommend the use of biological agents against them in the remote areas where they are suspected of hiding.
If these attacks are as major as Ijaz believes them to be those of us who manage to survive will be living a life that is unimaginable by today's standards.
