The Mexican government, through its consulates in the U.S., has been routinely violating American sovereignty regarding immigration matters. Operating on the premise that migration to the U.S. is a fundamental human right possessed by all Mexicans, Mexican officials here and abroad oppose the enforcement of immigration laws and seek to import Mexican culture to American schools and communities. Naturally, the Bush Administration turns a blind eye to these diplomatic incursions. I write about this growing Mexican cheekiness in the latest City Journal.
