The assault on the Mexican Embassy in Ecuador is the latest photograph of a turbulent panorama. The conflict between López Obrador and his counterpart, the right-wing Daniel Noboa, is the deepest that Latin America faces today.

Venezuela has just approved a law that unilaterally annexed part of neighboring Guyana, Essequibo. And in Central America, to the isolation of the regime of Daniel Ortega and Rosario Murillo are added the attacks of the Salvadoran Nayib Bukele on anyone who questions his security policy. These are some of the focuses of a territory of diplomatic conflict, writes Ruben Navarrette, the former head of the U.S. State Department in Latin America and the author of a new book on the region, "Turbulent Panorama: Latin America's Tensions and Tensions," which is published by Simon & Schuster on May 8. The book is published in English by Simon and Schuster, with Spanish subtitles.
