In many Western countries, including the United States, citizenship is considered a right that cannot be taken away except in very limited cases, such as serving in another nation’s military or having obtained citizenship fraudulently. Others strip citizenship from people who take another passport. Britain, along with Israel, is one of the few countries that can revoke the citizenship of dual nationals — even if they are native born — if they are suspected or convicted of terrorist offenses or acts of disloyalty.

I'm not taking a view on this; it's just necessary to be aware of what's happening.
