On the one hand, it is an honor that a certain someone is mentioned on this wedding invitation from the British Royal Family:
On the other hand, it makes it clear that he is not invited…(in fact, he was not):
The Queen personally invited 40 heads of state, who received the gold-embossed invitations over the weekend to the April 29 wedding of the future king.
The Obamas, however, were not among them. <source>
This is called poetic, and actual, justice for a man with such contempt for our anglo-saxon heritage and the UK, our great ally in a world of darkness.
