It just occurred to me: there might be one unique source of pressure to make Disney decide to yank "Path to 9/11" from TV: Apple.
Consider: Steve Jobs recently joined Disney's board, as a powerful new force. Jobs has never been outwardly political, to my knowledge at least, and seems to be more focused on business. But on September 12, just one day after the controversial movie is supposed to be broadcast, Apple is expected to make a
very important announcement about a new movie download service--and it is expected that Disney will be their primary, if not their only, initial source of media.
This could be a huge turning point for Apple, a very important event, and for their major partner to be disgraced in a media scandal the day before the unveiling--well, Jobs might very well want to avoid that. And that could very well lead to pressure on Iger to do the right thing--or at least the right thing for good business.
