Here is an article in the Telegraph, talking about a supposedly-in-the-works megahighway that would link, in one gigantic road, Canada, the US, and Mexico.
Texas is fighting a battle with it because they fear that the US would lose sovereignty.
WOW! That’s some freaky stuff there… The US is the 800 lb gorilla of North America; shouldn’t WE be fearing losing OUR sovereignty to THEM?
Any plan the US puts together would put them clearly dominant; they’ve got nothing to worry about.
