Imagine that one not very fine day two or three of your states in the Southwest, in the space of 24 hours, declare themselves independent of the U.S... declare themselves a fully sovereign nation, decreeing that Spanish will be the only language. All English-speaking residents, even if their ancestors have lived there for 200 years, have to take a test in the Spanish language within one or two years and swear allegiance... Otherwise they will not receive citizenship and be deprived of... (their) rights. Today Russia faces precisely this scenario.
