This is a good point. I've actually been surprised at how things have been going in recent weeks in regards to 'chatter,'or lack thereof. Then I remember all the stuff we know about al Qaida and wonder if something sinister is just over the horizon. You are probably right, they are likely laying low in many regions right now.
Or laying in prisons or graves. As I mentioned a while back, I think the bench may be working most things now and could well be getting desparate. This breeds carelessness which results in actions that disclose their identities and motives, hence the arrests of key players such as Khan.
