On the terrorist attack in Mumbai and the usual explanations about terrorists : he writes "....The best defense against this kind of murderous violence is to limit the pool of recruits, and the only way to do that is for the home society to isolate, condemn and denounce publicly and repeatedly the murderers — and not amplify, ignore, glorify, justify or “explain” their activities. ".
