The new head of Mexico’s Federales seems to think that the U.S. is inordinately concerned with terrorists sneaking across the border. “There haven’t been proven links to al-Qaida,” he said Monday of recent terrorist scares south of the border. What kind of proof does he want? We’ve broken up at least two organized rings, including corrupt Mexican officials, which had smuggled Middle Eastern illegals across the border, including one prominent Hezbollah official indicted in Michigan. Though Mexico is certainly cooperating with us, the security of our territory is not something we can contract out to foreigners, an idea implicit in calls for an increasingly open southern border.
