Believe that Obama's signature is the latter and is confirms his 'past' denied; and the dishonesty that unfolds from such deceit; and of course; beyond the hypocrisy of his message; the conflict of Obama's history of dates and documents that have his name assigned, might add to the 'slip' here.
Did wonder too, if the glaring error of 'wrong date' carried it's own message. It does 'cancel' the moment, the one, where Obama puts in writing, praise to England, and signs his name to it.
As to next faux pas reported; surely Obama was advised that the England's anthem would be played before 'anything' began at the table; including toast; but then, Obama has shown, time and time, again; jos arrogant indifference to protocol - including his determined 'bow' - which he mistakenly offered on behalf of every American citizen.
No question; Obama, 'on his own'; is his own worst 'instant messenger' and certainly, America's.
(And while I'm at it. . .if Michele had been wearing more suitable attire i.e. a 'suit' - and only, perhaps; even a hat - her skirt, dress. . .hair. . .would not have made her a 'victim' of the wind.) She is as slow or just as reluctant a 'learner' as is her husband. We know for certain, anyway; she is 'as determined'.
His “praise to England” is also a faux pas. He is visiting the United Kingdom, not just England.
The Queen is also not the “Queen of England” either. She is the Queen of the United Kingdom. There hasn’t been a “Queen of England” for 400 years.
