This is pretty funny - in yesterday's Wall Street Journal, the story from the UK was that the officials didn't even think this was an Al Queda plot and the Americans were jumping the gun!
It does matter, and here's why.
If it's an isolated group of nuts, when you capture the nuts you're done.
If it's Al Queda, you still have a lot more work to do, to eradicate the organization. And hopefully unraveling this plot will give us clues towards that goal.
