I dont’ trust Le Pen, but she is right on dual citizenship. You can only be loyal to one country at a time
I don't disagree, but loyalty is the test. Dual citizenship is often a function of the non "controlling" country. A US citizen who wishes to disclaim previous citizenship often can't. And frequently US citizens can't disclaim. Of course in LePen's case her objection is more focused. No dual Israeli or US citizens, other EU countries or Russia, that's fine. Which betrays a bias unrelated to the citizenship issue.
