Honestly, I would. Both princes have reason to humiliate him for the disrespect he has shown toward their mother and Harry's wife.

(on Twitter, of course) when Catherine's privacy sunbathing nude in what she thought was a private, remote location was egregiously violated.

I can't believe this visit is really going to happen. I am sure it will be a fiasco.

and rip it out like that cave rabbit in Monty Python and the Holy Grail movie.

I think Fat Donny gave/threw/drop-kicked his chance away! Actually,forget the drop-kick and throw cause that would require physical movement; so we'll just say "gave".

Maybe Harry will crush a few bones in Trump’s hand.

I and the rest of the world would love to see Donald writhe in excruciating pain and sob like a baby.

Wasn’t there a story about 45 saying he wished he’d had sex with Princess Diana back in the 80s? I’m sure the Royals haven’t forgotten though.

Only in your nasty wet dreams might that be true.

Like she would ever consider involvement with a slimebag like him

What would happen if someone in the royal family punched Trump in England, if course? The right would piss all over themselves. The rest of us would howel in delight. But what would happen next?

A few talks with the queen to calm him down..
After all he disrespected his mother and his wife..
What would you do in that situation? A well placed snide remark? crushed handshake? A wispered remark about Melania? No show?

He has a reputation for being blunt and speaking his mind. In a few sentences, he'd verbally decapitate Shitler. The Royals would be silently pointing and laughting - - and Shitler wouldn't even realize what happened.
