Latin Americans have a simple view of things. They view the Anglo Saxon north as their enemy. This goes back to colonial times. The enemy of my enemy is my friend. Naturally they will make friends with the enemies. South America was lost to the left over thirty years ago with the US paying inordinate attention to Europe and other areas, It practically ignored South America completely. Notice that the same oligarchy is still in charge. It’s the entrepreneurial and middle classes that have been decimated. The same pattern is being repeated here.
Ignored? Being an old fart with a flypaper memory, I recall the visit of Vice President Nixon to Venezuela in the 1950's. It was notable for the reporting of hostile crowds spitting on the Nixon motorcade and throwing rocks as he travelled to/from the airport. Then there was the Allianza para el Progreso in the -60's. The 1970's were marked by Carter's gambits into human rights, and the 1980's saw the Reagan interventions in various crises south of the border.
It is a misfortune for everyone that Central and South America are in the same hemisphere as the US. They would be better off in Asia or Africa where they could live out their miserable culturally collapsed existences without the Yanqui to blame for all their corruption and incompetence.
