Back in 2005 I quoted from Jason Burke's book on the best way to stop islamic terrorism;
"Currently military power is the default, the weapon of choice, in fact the greatest weapon available in the war on terrorism is the courage, decency, humour and integrity of the vast portion of the worlds 1.3 billion Muslims. It is this that is restricting the spread of al-Qaeda and its warped world view, not the activities of counter-terrorist experts or the military strategists."
So here's an example of how that approach gets results, from the New York Times/Observer section on 20th December and the quote is by Audrey Kurth Cronin of the National War College (can't find a URL!) talking about the arrest of some guys who were allegedly plotting some terror attacks;
"To me, the most interesting thing about the five guys is that it was their parents that immediately when to the FBI. It was members of the American Muslim community that put a stop to whatever those men may have been planning."
My guess would be that the parents are prepared to shop them in partly because they didn't agree with their sons actions and partly because they believed that this administration would give them a fair trial and not ship them off to be tortured. Another victory for human rights.
