Bingo. It's something that sets us above Republics. Who else remembers the Canadians looking down their noses and laughing at the Watergate debacle. The clever ones knew then what they had.
The system is perfect, a head of state, who keeps their nose out of things and carries little power except the ultimate power just is case it is ever needed.
The armed forces swear allegiance to the King or Queen and not the government.
Most Republicans can't understand or grasp the concept, they just haven't thought it through. If for instance a despot was ever elected in the UK the Crown has the ultimate power to remove them. Not only that, the Monarchy pays for itself in the money it brings in, it's a win win.
Remove the King or Queen to install another politician, haven't we had enough politicians? I have thanks.
