Travelers on Interstate 19 don’t need any “Welcome to Mexico” signs to know that the border is near.
Twenty-five miles north of the line, a giant white canopy stretches over the northbound lanes, with green-shirted border patrol agents and drug-sniffing dogs buzzing around the checkpoint. Farther south in Nogales, Ariz., green-and-white border patrol vehicles are as conspicuous as yellow cabs in New York, and stadium lights trained on the border fence dwarf the rustic Sonoran homes below.
Ten years ago, the permanent checkpoint, the stadium lights, and the ubiquity of those green-and-white cars would have seemed jarring. But since 9/11, America’s southern border has changed. President George W. Bush’s most famous surge might have been in Iraq, but along the US-Mexican border, he also presided over a doubling of manpower and a shift in the border patrol’s mission to make it a tool in the war on terror.
