What exactly does "stealth way" mean?
Let's figure this out logically. You mean Perry was somehow supposed to make a secret deal with some foreign company to built it (taking a kickback of course). Then secretly confiscate all the land needed from Laredo to the Oklahoma border. And then proceed with the building before anybody knew what was going on or could stop him.
And this was supposed to happen secretly in all the OTHER states too, from Texas to the Canadian border?
If this is what you mean then I'd like to recommend the book "The Death of Common Sense". And truly, I don't mean that in a nasty way.
This NASCO Highway is proposed to facilitate the moving of Chinese goods from the Mexican ports, through Mexican highways and through Texas and other states going up to Canada. This was done in a stealth way because it is in effect a federal highway since it links many states but in order to avoid congressional oversight, they decided to build the highway piecemeal—one state at a time. Texas would build its part right up to the Oklahoma border, then Oklahoma would build its part etc. etc. eventually going to the Canadian border. Mexican trucks would not have to stop at the border as they would have the new radio technology devices that would check them through.
Remember that there was a time about fifteen years ago when we would not have thought it possible that most of the items in the stores would have “made in China” on them. Nor did we believe that many American factories would be closed to Chinese labor competition, but it happened. It took lots of people, with lots of money and pull working together to achieve this. It appears that these same powerful business interests are also behind this. As far as paying off people, how many people do you suppose had to be paid off before NAFTA and the Chinese trade deals? Many if not most politicians are paid off in one way or another. They just do it in legal ways—honest graft.
