Some more questions to ask:
If there are other training camps; where are they?
What countries have jihad training camps and what are the locations of the camps?
How many “westerners” (including Americans) have been trained in these camps?
How many of these “trained” westerners (including Americans) have returned to their home countries?
How many westerners (including Americans) have been trained via the internet?
Well, something to think about.
