Absolutely. Our massive military sure hasn't done the job. OBL has evaded our best efforts and at the same time, here we are performing "nation building" excercises which have nothing to do with the task at hand.
Furthermore, releasing the hounds of hell on OBL from a varied group of professional soldiers and computer hackers would render Al Quaeda impotent while at the same time saving taxpayers billions and reducing the possibility that we will be intractibly involved in the internal affairs of nations which neither appreciate nor need the "help."
Politically, this "war on terror" is a minefield. And it exposes us to even more terrorism.
Capturing/disabling OBL was never an objective; it was desirable, but not an objective. Who knows, it may have been done - we haven't heard from him in 3 months. As far as nation building goes, I would partially agree with you. Afgansitan was already in a war before US troops arrived, we simply tilted the scales to favor the N.Alliance. There seems to be little objection to the change in power.
Where would we get these hackers and professional soldiers that you mentioned? Why would we use them instead of a small Delta Force contingent? Are they ready to go now, or would they require a couple of months of preparation? Who is accountable if they fail, or if they take too long? What would be their objective? How will they function in a manner that doesn't interfere with the internal affairs of Afganistan? How completely could they eliminate the problem of terrorism so that we would not have a reoccurrance of the WTC?
I ask these questions not to put you down. I believe that it may be a viable solution in the Iraqi situation. However, the Afgan situation required an immediate response and a show of force in a situation where the objectives were unclear because we lacked adequate intelligence.
