Mexican officials here and abroad are involved in a massive and almost daily interference in American sovereignty. The dozens of illegals milling in the consulate’s courtyard as Velázquez-Suárez speaks, and the millions more radiating outward from Los Angeles across the country, are not a naturally occurring phenomenon, like the tides. They are there thanks in part to Mexico’s efforts to get them into the U.S. in violation of American law, and to normalize their status once here in violation of the popular will. Mexican consulates are engineering a backdoor amnesty for their illegal migrants and trying to discredit American immigration enforcement—activities clearly beyond diplomatic bounds.
Mexico’s governing class is not content simply to unload the victims of its failed policies on the U.S., however. It also tries to ensure that migrants retain allegiance to La Patria, so as to preserve the $16 billion in remittances that they send to Mexico each year. Mexican leaders have thus tasked their nation’s U.S. consulates with spreading Mexican culture into American schools and communities. Given the American public’s swelling anger about illegal immigration, it’s past time for Washington to tell Mexico to cease interfering and for the Bush administration to start enforcing the law.
