Bruce is a cool guy, but nobody died, and made him king.

We have evidence that NSA is using social engineering to weaken
protocols and implementations. Incidentally, when it comes to IPsec 
this pattern has been independently corraborated by other parties I 
happen to trust. This is no proof, but we need to become very
careful about preventing such security meltdowns in future.
Because this *will* happen, again.

Come on, that the mainline inclusion is a major political
snakepit is pretty well known. I don't know whether spooks
are pulling strings behind the scene to fan the flames, but
if they don't they're really lousy at their job.

I can tell you that I would be very interested who commited
all the crypto regressions into Debian. I really hope that 
someone is going to review the checkin history, and writes
a report about it.

This is a war, and there will be innocent people hurt. This is
regrettable, but we didn't start it.

What we need to let go is personal sensitivities. If you check
in crap code that breaks things, whether you're an NSA mole or
just incompetent, it doesn't matter. You need to have your checkin
license revoked.

Same thing applies to package signing secrets of Debian.
Unfortunately, we can no longer afford to be negligent there.
