Jacko,
ignoring John Walker Lindh, Adam Gadahn, Jose Padilla et al,
Quite the contrary Jacko....those cases are proof of what I am saying. They took up the Terrorist track but were not dedicated enough to commit suicide to accomplish their deeds.
Lindh was in Afghanistan when captured, Padilla had intentions of building a dirty bomb but nothing suggests he had suicide bombing as the method.
We have our malcontents but none that are happy to sit atop that Pyramid of dedication....the one with the very broad base of folks that nod "uh huh" when they read or hear of something and is topped by those that gladly die for their cause. Oddly enough it is almost the opposite to a Pyramid drawn for those willing to defend freedom.
