I suppose you get what you deserve. The Obama's will not be invited to William and Kate's wedding.
There may have been a possibility of invitation, had the wedding happened a few years back, you know, before giving a nearly blind Prime Minister a state gift of 25 DVDs, in a format that doesn't work in Europe, or giving the Queen of England an iPod filled with show tunes and your own speeches.
What a foreign policy buffoon. Karma's a bitch, eh, Barry?
