Good for her!
Elizabeth II has been a great asset to the British as they transitioned away from Empire and into the Commonwealth. She’s been a steadying influence during times of crisis from World War II, throughout the Troubles, on up to the 7/7 attacks and beyond. It is true that her role is almost entirely symbolic, but that’s ok; there’s nothing wrong with having basically a powerless mascot for your country.
So good for the Queen and good for the UK!
