Foreign Policy‘s Dan Drezner on the new Al Qaeda and threat escalation:
That said, I’m going to continue to insist that the United States faces a much less threatening threat environment now than it did fifty years ago.
I reached a similar conclusion here using Richard Ned Lebow‘s counterfactual method. As did John Mueller, and Adam Curtis in his documentary The Power of Nightmares (2004). September 11 could have been much worse.
