Anyone with a simple knowledge of the history of western civilization understands the special status of the Vatican and why it is treated as a state. It has more historical legitimacy than many other nation-states out there.
Its independence was granted by Mussolini, so no in my view it is not legitimate unless you consider Mussolini legitimate.
No. Just no.
He has a decent point there. Not that I am saying it is sane to support not recognizing the Vatican.
His point fails miserably because he's saying that executives of sovereign nations should not be recognized if they suck. I cannot begin to describe how insane that view is.
