With just the towers there will still be many who will or will attempt to cross and there will be a lot of shooting and then I believe we(the USA) will be blamed for a lot of carelessness, etc., and the whole thing will blow up in our faces in the global community.

What about stopping the terror right here at home.  It is the least we can do to help show our young people in Iraq we are doing our part here. Janie
