A major bust by U.S. drug authorities targeting Mexico¡¯s fastest-growing gang will likely do little to stem the rise of the ultraviolent Jalisco New Generation Cartel (CJNG) and its shadowy leader, Nemesio Oseguera Cervantes, alias ¡®El Mencho.¡¯

Over the past decade, Oseguera, a 53-year-old former policeman, has masterminded the CJNG¡¯s emergence as a criminal empire spanning five continents and a rival to the Sinaloa Cartel of captured kingpin Joaquin ¡°El Chapo¡± Guzman, now in a U.S. prison.

From the swathes of Mexico¡¯s western Jalisco state that he controls, Oseguera is accused of flooding U.S. streets with synthetic drugs such as methamphetamine and fentanyl, that cause tens of thousands of deaths every year.
