Actually, he wasn't claiming responsibility.
He was just applauding the actions.
He was just applauding the actions.
Wrong. Do a search and read the transcript. Among other things said by Osama:
He identified Mohammed Atta by name as the leader of the attacks;
He makes the point that they did not expect the towers to collapse, just the floors above where the planes hit;
Also says that most of the hijackers did not know the details of the attacks until just before they occurred.
Now, this was not a face-on tape saying "I ordered the attacks." But he had the meeting taped, and then had the tape delivered to the news media. Sounds to me like he was claiming responsibility.
