A two-sided fence

MEXICO CITY — Mexico’s economy is being dragged down by the recession to the north. American addicts have turned Mexico into a drug superhighway, and its police and soldiers are under assault from American guns. Nafta promised 15 years ago that Mexican trucks would be allowed on American roads, but Congress said they were unsafe.

United States-Mexican relations are in the midst of what can be described as a neighborly feud, one that stretches along a lengthy shared fence. That border fence, which has become a wall in some places, is another irritant.
