That's what Heads of State do. Nothing out of the ordinary there, apart I admit from the hugely successful visit to Ireland which was indeed historic, given that Britain occupied that territory for 800 years. Irish people are very welcoming though.
The trips to the Caribbean, Canada, Oz and wherever else are relics of the ermine robed leader deigning to visit the Imperial subjects, or it was, but Britain is locked in a post colonial crisis of sorts right now, which I believe led to Brexit. You know, the exceptionalism of a small island just because they fought in the war and had an Empire once.
Anyway, from my perspective it is nothing personal, because I do not know any of them personally, but the image they portray is not one of hard work, humility or intelligence either. They were just born, like me.
