When at the CIA, I was fond of saying that many jihadis join the movement for the same reasons that young Americans join the Crips and the Bloods: youthful alienation, the need to belong to something greater than self, the search for meaningful identity. But it also matters what gang you join.

The CIA held about a hundred detainees from 2002 to 2008; about a third of them underwent interrogations that have been variously described as enhanced, tough or torture. The toughest technique was water boarding, used on three detainees, the last in early 2003.

All enterprises and major players need to pay attention to the needs of the government of the country of which they are a part. At one level, it would be unconscionable for a company like Huawei not to be responsive to Chinese national-security needs.

I must admit, my old tribe is not unanimous on the view I've taken, but there are other folks like me, other former directors of the NSA who have said building in backdoors universally in Apple or other devices actually is bad for America. I think we can all agree it's bad for American privacy.

In my own private-sector work, I have become intrigued with RIWI, a Canadian based company that surveys random respondents on the Web to measure attitudes in otherwise hard-to-reach places.
