In a significant development on the frontlines of the drug war, Nemesio Rubén Oseguera Cervantes, also known as El Mencho, was killed by Mexican forces during a military raid in Tapalpa, Jalisco, with crucial intelligence and military support from the US. This operation marks a pivotal moment in Mexico's battle against the CJNG cartel, but has led to violent retaliations that raise urgent concerns about the region's stability and the ongoing effectiveness of US-Mexico cooperation in combating organized crime.
