They do not need an explanation, they are in the very act of accomplishing the dirty deed right now. We may not get the hundred-million plus, instantly, but with the birth-rate, the next generation could easily approach that number. Bingo, bango, bongo, we no longer have what could be called an American culture.
They don’t need no stinking explanations, like they don’t need no stinking badges (though they do use them when they have to and they are usually very high-ranking badges).
LOL!

The current population of Mexico is about 109 million. If we merge, how is that not instantly?
Incrementalism.. First you have a large number of dual citizens to Mexico and America. Then make it easier for Mexicans to get temporary jobs in America. Then easier to get full time jobs, and ‘path to citizenship’. Make travelling easier, and it will increase as they visit relatives who are american citizens working in america, and travel the other way. Hundreds of thousands of Americans work in Mexico too I believe.
Then gradually loosen and loosen the work visa rules with Mexico so its very easy to work in both countries. When the final merging is done, its not that big of a jump, as the countries will mainly be integrated. Harmonizing regulations is another aspect, and ultimately harmonizing regulatory authority. Like this is doing with airlines. Which we needed to update our airline traffic system anyway.
