Re: What is he actually saying
It's all very nice but the maths still don't add up. Anyone who deliberately weakens encryption will negate their encryption, if not immediately, then sometime soon.
To me this sounds more like an elaborate re-hash of the "there must be some way to do it" school of thought. Now it is being trotted out by a guy whose business is to keep secrets. I suspect he is trying to keep the more rabid Alzheimer sufferers in Congress happy (a certain California senator comes to mind) until either he or they can retire on their government pensions.
So sad that the informed reasoning of the few can be so easily sidetracked by the uninformed reasoning of the many.
If American companies do attempt to impose global (HW or SW) back doors on the world, then the stampede to produce alternatives to American products will be deafening. This is precisely why it won't happen, grand-standing politicians aside. Brennan clearly knows this but can't say so. His is a smoke blowing exercise because economic suicide is not the answer.
