The president of Honduras has been tied to the country’s drug-trafficking industry by U.S. federal prosecutors. El Salvador’s president is an authoritarian, whose allies recently dismissed five Supreme Court justices as well as the attorney general to seize control of the top court. That’s why Harris is leaning on Guatemala as the best hope for making early progress in her efforts to address the poverty, corruption, violence and other destabilizing conditions that are driving thousands of people to migrate north and seek refuge in the United States... For now, the administration is most optimistic about Guatemala as the place to make headway, not because it’s absent of corruption, but simply because it’s willing to talk about the tough issues. And it’s not Honduras or El Salvador. But former officials and experts warn: If Harris focuses solely on cutting migration, efforts to improve conditions in Guatemala and the rest of the region will fail.
