Of COURSE it was intended to offend the Muslim sensibilites!! Why backtrack? He KNEW it would offend them!
Actually, his speech was aimed at that part of the muslim community that claims that islam isn't violent (all three of them) and not at those who spread the faith by the sword IMO. He is upset that they are offended instead of responding rationally.
It was not intended to offend them. It was intended to say what it did and curse violent jihad. He's sorry if its offensive, not sorry that he said it.
