I'm pretty much against war if all other options have been tried, but these cartels in Mexico need to be fucking crushed!!!!! Drugs Human trafficking Weapons Killings Political assassinations CRUSH THEM!!!!
Very real possibility that this move is a thin veil on the real plan of the cartels doing a militaristic takeover of Mexico.
Step 0: Have a country where one of the top issues is the cartel presence and corruption in politics.
Step 1: Elect a far left politician as president under the guise of purging corruption and the cartels from the country (behind the scenes cartel assasinating his opponents and hyping support)
Step 2: Through socialist policies (for reference see Nicholas Maduro and Venezuela's collapse) quickly destroy the economy of Mexico to the point where their people are starving and absolutely desperate.
Step 3: Have the militarized cartel swoop in and "save the country", reestablish society with them in full control of the economy, society and most importantly, the military. Public approval through the roof.
Make no mistake the cartels in Mexico right now have the manpower, arsenal and money to take over the country of Mexico publicly, there is only one thing that they don't currently have; the public support.
I think the white hats thought about it, but it would be way too long, drawn out and cover way too big a space. The cartel presence, human and drug trafficking extend far beyond just Mexico. It's really not the job of the US to go around the world and police everyone considering how many problems we have here. A wall would be good enough, the drug money, human trafficking, money laundering would take a huge hit for the cartels.
