Yes, the pope is said to be sorry for being misunderstood and that he got misinterpreted.
I also feel sorry that he got misunderstood and misinterpreted.
I also say this: Benedict is too smart as that he would not have known what would follow when holding that speech with that quote. Read some of his stuff and realize his way of clear thinking and knowledge, and then tell me that he could have missed this after the muhammad cartoons just gave an example. I think it was intention, a calculated attempt to give Westerners another push to open their eyes and realize the true nature of Islam. And the Islamic world is stupid enough to deliver exactly the reaction that was ordered, by that illustrating, that it indeed does not agree with the pope's conclusion in that speech that religion shall not be spread by the sword, and that violance cannot replace reason and logical persuasive power when advertising religion.
