The terrorists don't have to blow up a plane ... they just have to keep the American public fearful ... and the TSA is doing that job nicely ...
That reminds me of one of my worst predictions ever. Around September 12, 2001 I expressed the view that the 9/11 attacks would mean the end of Islaamic terrorism. As Bob said, the idea of terrorism is to terrorise, not to maim and kill innocents. I thought this was just a much bigger version of the Omagh bombing which also killed innocents (on a much smaller scale though) and caused such revulsion that it effectively brought about the end of Irish terrorism by completely choking off any moral support.
Sadly, I was dead wrong.
