Also, Scotland tried to break off from British rule, look how well that turned out.
There is also the Brexit, not sure how that is going, but it shows that the Queen and the British Pound are independent from the E.U.. Notice how the Pound never went away? Where are all the French Dollars? There has been a historical rival between the French and the British, to see France tied up in the Euro, probably put a smile (only inside of course) on the Royal Queen.
The U.K. is very powerful, they are not to be undermined in any way. Not sure if it's true, but there are rumors going around that Prince Charles will assume the role as King of England next year, but there is also historical statements that the Queen will serve her whole life. Correct me if I'm wrong here.
