as I think I posted once before somewhere,Does the phrase "Maginot Line" ring any bells?
And I can almost hear General Custer yelling, "I got one, boys...keep firing!"
If we have enemies who really decide to 'get' us, they won't NEED missles...little a-bombs in U-Haul trucks will do fine. Peter T & Alex said it it just fine, this is BOTH "pork" and useless.
