Two quick hits:
First, a roundup of the large Islamist terror cell busts in over six countries yesterday and over the last few months, provided by the frighteningly erudite Jeff Goldstein at Protein Wisdom. The biggest cell was in Canada, and had at least 17 members who had assembled 3 tons of ammonium nitrate (the material used in the Oklahoma City bombing). One worrying thing for me is that several of the terrorists from different countries had met in person in Bangladesh, a country wracked by Islamist terror yet largely ignored by the Western counterterrorism effort.
Second, a fascinating discussion of trends in counterterrorism over at the Belmont Club. (A few acronyms need to be defined. COIN: counterinsurgency operations. GWOT: global war on terror.) Read the whole thing, plus as much of the comments as you can.
