No, not really.  OK, I'll admit the threat/danger is worse but not an order of magnitude worse.  Not so much worse that the rules of the game need to be altered.  Talking of the terrorist threat in terms of WW3 is just blowing things completely out of proportion.  The US and UK governments are whipping up a frenzy of completely irrational fear about terrorism to allow them to push through draconian freedom reducing measures that are completely unnecessary.  Did you see the Power of Nightmares documentary series?  It showed just how much this "unprecedented threat" has been grossly overstated. 

It's saddening to see that so many people have been taken in and that as a result the terrorist have pretty much already won
