In modern times, the charge of dual loyalty is often applied to Jews outside of Israel. Such accusations of dual loyalty are generally considered to be a form of anti-Semitism, especially when no additional justification for the charge is given.
Similarly, Catholics have been accused of dual loyalty due to their affiliation with the Vatican and the Pope; in particular, this was widely urged in the United States as a reason not to vote for John F. Kennedy for president in 1960.
