Considering as a country , we foolishly allowed the bulk of the nations freight to be moved by truck , instead of rail , like almost all other industrialized nations on earth , and not developing infrastructure to help get rid of the automobile , we are vulnerable to all kinds of attack . A few strategic detonations here and there , would throw the wrench into our daily life very easily . I think now would be a good time to start rationing gas again , like in WW2 . Then ….and only then , would you see a return of infrastructure development . Especially in the form of rail .
