Context: Migrant Caravan
As the midterm election campaign entered its final days this past week, President Trump stepped up his rhetoric about the so-called caravans of Central American migrants making their way through Mexico to the United States. He described the movement of people as an “invasion,” and says he will send as many as 15,000 troops to guard the country’s southern flank. But other commentators emphasized the 1,000 miles the migrants would have to travel before reaching the US border, the slow pace of their journey, and the possibility that many or most will opt to remain in Mexico. Newsweek, citing Pentagon documents, reports that officials expect “only a small percentage” of the migrants to actually complete the march to the border — maybe 20 percent, based on historical patterns. That means about 1,500 migrants total.
