To the citizens of the United States of America from Her Sovereign Majesty Queen Elizabeth II.
In light of your failure in recent years to nominate competent candidates for President of the USA and thus to govern yourselves, we hereby give notice of the revocation of your independence, effective immediately. (You should look up 'revocation' in the Oxford English Dictionary.)
Her Sovereign Majesty Queen Elizabeth II will resume monarchical duties over all states, commonwealths, and territories (except North Dakota, which she does not fancy).
Your new Prime Minister, David Cameron, will appoint a Governor for America without the need for further elections.
Congress and the Senate will be disbanded. A questionnaire may be circulated next year to determine whether any of you noticed.
