Maybe they plan to detonate a nuke underwater near a harbor.

What nukes? Whose nukes? These guys don't have nuclear bombs. And if they did, detonating one underwater near a harbor would hardly be the easiest and deadliest course of action. Are you referring to a "dirty bomb?" How much damage could that do underwater?

I still contend that if they had access to or possessed WMDS they would have used them on 9-11, period.
