Latin America is tired of being treated like the help by the U.S. From Patrick Lawrence at consortiumnews.com:

I tip my cap, as we all should, to President Andrés Manuel López Obrador of Mexico. And to Presidents Luis Arce of Bolivia, Xiaomara Castro of Honduras, Alejandro Giammattei of Guatemala and Nayib Bukele of El Savador. They all pointedly declined to join President Joe Biden at his Summit of the Americas in Los Angeles last week, joining to protest Biden’s refusal to invite Miguel Díaz–Canel, Nicolás Maduro and Daniel Ortega, the presidents of Cuba, Venezuela and Nicaragua respectively.
Add it up. Eight of the region’s 33 nations were absent when Biden convened the summit “to demonstrate the resurgence of U.S. leadership in the region,” as the government-supervised New York Times forlornly put it. Don’t they ever get tired of these long-exhausted phrases over on Eighth Avenue?
“There can be no Americas summit if all the countries of the American continent do not participate,” López Obrador explained at a press conference announcing his decision. “Or there can be, but we believe that means continuing with the politics of old, of interventionism, of a lack of respect for the nations and their people.”
