Unrealistic? Its working for Israel keeping Hamas from blowing them up. China built one over 2000 miles long. No whats unrealistic is "the virtual fence". I agree with Rush. If its such a great idea, lets see how well the capital and white house do with a virtual fence.
I wonder how many people would want to have virtual locks on the virtual doors to their homes.
It is this kind of deceptive wordplay that I find most aggravating by those who clearly do not want to do anything at all about creating a barrier.
