This highway/road is a dagger aimed at the heart of the USA. A 30 lane super highway, included rail, telecommunications and pipelines starting in central/coastal Mexico and running to Canada with branches going east and west in central continental USA. What more could an invader ask for? Yeah and Gen. Ike is rolling in his grave at such a proposition. Yuh know President Eisenhower who gave America the current Interstate highway system, which of course you jpsb, never ever use.(/sarc)
Big difference Dane, internal networks of highways not the same a continental superhighway that starts at foreign ports. To bad you have zero skills in military science. Folks that got upset at Chinese taking effective control of the Panama Canal will go (rightfully) ballistic over this lame brain idea, from a national security view.
The economic view is not much better, pipe lines good, 30 lane continental super highways bad.
I'm sure this idea will make the open border crowd very happy. Once finished any and all from parts WAY south will have a wide open road into the most of USA or Canada.
