never mess with Mother Nature.

we really need to tighten up our border security, and address the problem from the demand side. It is the only thing that makes sense after decades and billions of dollars chasing a chimera abroad.

better to spend the money on treatment, enforcement, interdiction, and security here at home.

I used to be a fan of interdiction and suppression efforts abroad....until I saw them failing at close range in Perú in the early 1990's.

Economic development overseas can also play a role, but...we are talking about massive, Marshall Plan dimensioned initiatives, and with our current priorities, there is no global will for that sort of engagement and investment.
