Mexico's experiment in the enfranchisement of dual nationals undermines the very nature of citizenship. Both dual nationality and dual citizenship threaten the integrity of nations. And dual status puts individuals in precarious situations. It uproots the civic commitment necessary to preserve a nation and runs counter to fundamental American civic ideals. The existence of a nation rests on the mutual commitment of all citizens to the common good.
Citizens rely upon their nation's government to safeguard the interests of the whole.
In turn, the nation counts on its citizens to promote the national interest - serving in the military, obeying the law, holding public office, voting, and being faithful. If America continues to allow dual status, the nation-state cannot last. We either have nations or we end up with a global governing body. And no globalist bureaucrat will ever have the incentive to protect the rights and liberties of an individual across the world as does the local mayor or a state legislator, who lives in the same community and shares the same civic needs. Those who hold dual nationality or dual citizenship owe allegiance to more than one nation.
