I think the attacks today just show that an attack against the United States could take one of many potential forms.

Because this attack used commercial airliners does not increase or decrease the possibility that a future attack could take some other form.

I think the real goal of this push for NMD is in reality that it will result in technology spin-offs that will greatly enhance theater missile defense. It we actually get NMD in addition to TMD then great...We need both.

Incidentally, a effective TMD located on the roof of the Pentagon would have saved hundreds and perhaps thousands of lives.
