I am not really trying to open up that giant door of politics. I just feel the need to point out the obvious. I don’t know how the people of the United Kingdom really feel about the queen. If often appears to me that she stays away from politics and simply concentrates on her family. I don’t know her role.
If you are looking at “image” and “grace”, I think you would have to recognize that welcoming the President of one of their allies with a handshake is more productive that a giant balloon.
So perhaps some should take a “lesson” from the Queen on civility, decorum and diplomacy.
