The Internet Archives has put together an interesting collection of videos from about 20 television networks worldwide called Understanding 9/11. There is reported to be 3000 hours of footage from 2001 which the user can pinpoint by the minute. A collection of essays about the events is also posted.
The anniversary seems to be an opportunity to revisit and reassess our recent history. It may be too much to hope for a lessening of polarized political positions, but I'm hoping anyway.
