Option 5:
Detonate some nukes in the upper Atmosphere of Continental Europe, firebomb the fuck out of any favela/narco farms to get rid of old surplus while pleasing the milindustrialists, then invade Mehico genociding any remaining inferior men and turn it into a nip style colony with state mandated birth control for the locals.
Russia will be busy conquering Europe and the western Internet will be severely fucked so telling the american public the Mexican government was run by anti-semitic nazi cartels lead by zombie hitler distributing hate substances all along should be good enough.
