The airline part is good. The highway part is bad. And this does not erase national boundaries.
Ever heard of the word "incrementalism"?
That's what is happening. The end goal is the erasure of America's sovereignty, Canada's sovereignty, and Mexico's sovereignty.
And if you think you'll be hearing an overt announcement concerning this (yet)....that would be foolish of them. There's too many people, from each country, who would revolt.
Incrementalism allows the sheep to stay asleep or watch American Idol as they sip their lattes.
