I dunno, I've always thought that The Queen had more savvy than to make an early invitation to President Trump, even though through  PM May.

Her visit to the US seemed so eager and hopeful....nauseating really......we have no idea at all of how far Pres. Trump will go in messing up the world and yet there was Britain's representative almost seeming to say:  "Let's be best buddies, we're in a real pickle in Britain and we could use all the help the US could give us!" 

 Doesn't she realize that under Trump's leadership, such a friendship could be nothing but a curse?
