However two comments relating to Mexico strike me as extraordinary, when they are in the same article:
The US has room to grow and it manages immigration well.Okay, that's a reasonable belief. Honest people can believe that the level of immigration to the USA is either good or bad. However when the same author writes:
Many areas of northern Mexico that the US seized are now being repopulated by Mexicans moving northward - US citizens, or legal aliens, or illegal aliens. The political border and the cultural border are diverging.Until after the middle of the century, the US will not respond. It will have concerns elsewhere and demographic shifts in the US will place a premium on encouraging Mexican migration northward. It will be after the mid-century systemic war that the new reality will emerge. Mexico will be a prosperous, powerful nation with a substantial part of its population living in the American south-west, in territory that Mexicans regard as their ownIt seems inconsistent to say the least. If the second prediction were a remotely plausible outcome then the USA's current management of immigration is catastrophic. One of the measures of success when considering immigration is surely "Not likely to lead to secession of large part of country".
* That said some predictions made in the 18th and 19th centuries that power would move from Europe to North America & Russia turned out to be accurate for the 20th century.
