With at least 25% of their fighting age men in the USA, now would be a good time to do it. They're saying half of the entire state of Zacatecas is living in the US --- something is seriously wrong when that many people leave their homeland. No end in sight.
Hmm. An out-of-the-box idea struck me: VERY conditional amnesty in return for service in an American foreign legion to liberate Mexico. Once their service was completed, they wouldn't be granted automatic residency in the US, but they wouldn't be permanently enjoined from reentry for short-term visits (day trips for shopping, tourist visas, et cetera). They'd be eligible to apply for legal entry into the US under the standard quota. Exceptional heroism would earn some sort of head-of-the-line priveleges in that department.

In the 19th through mid-20th centuries, we could tolerate a feudalist Third World nation on our southern border, because the US southwest was an arid wasteland with no means of rapid travel elsewhere. Now, we can't.
