“Immigration” on our Southern border is the reconquest of territory lost in the Mex-Am war and the territory they sold in the Gadsden Purchase. Just because no one know the history doesn’t change this.
From infogalactic, the treaty of Guadalupe Hidalgo, which concluded the Mexican-American War
The treaty gave the U.S. undisputed control of Texas, established the U.S.-Mexican border of the Rio Grande, and ceded to the United States the present-day states of California, Nevada, Utah, New Mexico, most of Arizona and Colorado, and parts of Texas, Oklahoma, Kansas, and Wyoming. In return, Mexico received $15 million ($410 million today) – less than half the amount the U.S. had attempted to offer Mexico for the land before the opening of hostilities – and the U.S. agreed to assume $3.25 million ($89 million today) in debts that the Mexican government owed to U.S. citizens.
And the Gadsden Purchase, also from Infogalactic.com
The Gadsden Purchase (known in Mexico as Spanish: Venta de La Mesilla, “Sale of La Mesilla”) is a 29,640-square-mile (76,800 km2) region of present-day southern Arizona and southwestern New Mexico that was purchased by the United States in a treaty signed on December 30, 1853 by James Gadsden who was the American ambassador to Mexico at that time.
I’d rather the real French tried to recolonize the Louisiana Purchase.
1,000 years from now the story will be told of a 700 year back and forth conflict between the descendants of Spaniards and English in the Western Hemisphere.
