Charlie Black, an adviser to John McCain told Fortune magazine that the assassination of Benazhir Bhutto in December helped McCain, and that another terror attack in the US would too:
The assassination was an "unfortunate event... "But his knowledge and ability to talk about it re-emphasized that this is the guy who’s ready to be commander in chief. And it helped us.”
Then, the article paraphrases Black: "As would, Black concedes with startling candor after we raise the issue, another terrorist attack on U.S. soil.‘Certainly it would be a big advantage to him,’ says Black"

Here, Black "apologizes"

Actually, we should thank him for revealing what certain people may be thinking about.

I found this item where Stone says - careful, I'm translating from Spanish, which is in turn a translation from the Arabic here
"I've never believed the official story about the terrorist attacks on the Twin Towers in New York, and I've never believed the wars in Afghanistan and Iraq were a direct consequence of them."
The AP does cite the interview, but only her comments against the wars:

The Association for the Truth about September 11th (Asociación por la Verdad sobre el 11 de Septiembre) held a successful educational event on 9/11 in central Madrid on Friday night, featuring three separate talks on the cover-up, building 7 and the world after 9/11. Turnout was a respectable 20-25. Particularly interesting was the last talk by Juan Fernando, where he outlined the essential points of the psywar initiated with 9/11, in which the Bush regime and its media managed to make the 9/11 myth a semi-religious, sancrosanct belief.
