Well, this thing at Ft. Dix. Where the jihadi-babies planned on massacring Soldiers?
Look, al-Qaeda is what, "the base" in Arabic. What we're starting to see is the "free-basing" of jihad. The spread.
At the end of the day, the Osama's and such will fade, as early adopters usually do. The threat will develop from a myriad of "insurrectionists", and come at us from many angles.
All that will unite them is al-Qaeda's way of war, even as we pose over the next year, some Hamlet debating "to war, or not war."
We can debate the question, but I think it's already been answered.
