Pressuring or forcing dual nationals to renounce one of their citizenships communicates that love of country must equate to love of the country’s government – as opposed to communicating government’s duty to earn the love of its citizens.
For as long as man has kept written history, leaders have recognized that dual nationality is a tool to keep the peace. Emperors and kings frequently married the offspring of rulers from other nations thereby creating a dual national in their spouse while encouraging peace and cooperation between the nations.
