If an armed invader was pouring across the Mexican border would we stand helplessly by wringing our hands and let the invaders take the country?
Whether the invaders are armed or unarmed, the result is the same. The invaders occupy territory, seize resources and change the laws, custom and language of the invaded country.
No civilized nation in the past has ever survived such a massive demographic shift as we are being subjected to.
And no great nation has ever been invaded by 12 to 20 million invaders. Even the Mongol Horde did not number that many.
What, expect them to do their jobs?
“At the time of Ghengis Khan’s birth in the 1160’s, they were a loose group of about 30 nomadic tribes in a constant state of turmoil. They are believed to have numbered between 2 and 3 million.”
So you are right, the number of illegals was about the same as the Mongol Horde in the 1986 amnesty, and is now 5 to 10 times as large.
