Have you read the speech? Hardly an apology!
 This from The Guardian"
"He invoked the struggles for civil rights in the US, against apartheid and slavery, urging Hamas to follow the path of non-violent resistance. From any of his predecessors, that would have rung hollow. From the first African-American president, it carried great weight.

Obama navigated perilous terrain. He urged the Muslim and Arab world to embrace democracy, women's rights and economic development – difficult to do from the capital of a sclerotic regime. And when he called on the Muslim world to respect women's rights, he stressed his respect for the hijab and his opposition to westerners "dictating what clothes a Muslim woman should wear".

Whether this sensitive, supple and sophisticated speech will be remembered will depend on whether the rhetoric of respect is matched by a change in action. And that, as Obama admitted, is more than the work of one day."
