Quote from Hansel H:
Obama is the most powerful man in the world and yet he comes across as regular guy. He probably doesn't believe in protocol or any of the rest of this shit that's kept international relations formulated and inflexible for thousands of years. Michelle's putting her arm around the Queen was a natural human gesture that was reciprocated by Her Majesty.
Due to his determination and intelligence, Obama may well turn out to be America's greatest President and a world leader of unprecedented influence. He's the most energetic President since Teddy R. but he has a much finer intellect.
By and large world leaders are neurotic, narcissistic, power-seeking screwups; this time we have a leader who's a normal human being.
In any case, the rest of the world will have to accept the Obama's style; they're the most powerful couple in the world and the rules of protocol may have to be adjusted to reflect this fact.
Just be grateful Michelle didn't give her the tongue.
