9/11 in Realtime
If you want to get a handle on how the War on Terror started and how everybody felt about it, I highly recommend listening to some of the live radio shows from that morning, such as the Howard Stern show. You look back now and question how we could've let it get so out of hand, but watching people react to it in real time takes you right back to the emotions it triggered. I don't think I've ever felt that degree of collective fury before. That week, many of the people I know would've been happy to launch nuclear weapons at every population center in Afghanistan and the capitals of every nation that'd so much as looked at the United States funny in the previous ten years.
