Things are not going so well in America Central right now. Things are not going too much better in Mexico, either, of late.
A lot of people living in Tijuana (at least the Hidalgos) are saying "Hacer México Grande otra vez" right now.
I tend to agree with sending Troops to the Border.
This is a difficult and sensitive Civil Affairs ("CA") and Civil Military Operations ("CMO") (and, potentially, Counterintelligence ["CI"]) mission . . . and the US Army (in particular) has gotten very good at these tasks in the last 17 years.
Some of these events are fallout from the Frente Farabundo Martí para la Liberación Nacional ("FMLN"). Insurgency in El Salvador in the 1980s and early '90s and the fallout in Honduras of that Insurgency.
Some of it is the result of the disintegration of Venezuela, the most contiguous country in America del Sur.
Some of it was young Salvadoran refuges from the war starting a successful street gang in Los Angeles with the cooperation with La Eme ("The M" or The Mexican Mafia), a US street/prison gang of great power and influence, and that entity (known as "MS-13") leaking back into America Central to create what amounts to an alternative government.
I don't care if this is our fault or not (but, can we talk, we clearly contributed to this), but we are stuck with it and need to take appropriate action (CA, CMO & CI-type appropriate action).
Some people have been saying this is an invasion. It isn't.
It is something potentially worse: a mass migration, something that does not benefit more settled populations.
We have to get control of this. We also have to act justly. This requirement is intensified by the 24 Hour News Cycle, but it is far older.
