Evidently they have plenty of other sources to deal with... their SIGINT
charter is to read traffic, not necessarily to decrypt traffic. It does
seem excessive, though, and it will seem even more excessive once more
traffic is encrypted with strong systems and plaintext begins to disappear
from the airwaves and wires. It bothers me that the gov't appears to
be redefining the role of the intelligence community to be economic spying
rather than the military spying that was (I think) justified during the
Cold War. Rather than finding ways to justify and maintain current budgets
and bureaucracies, why not just cough up the peace dividend?

I misstated his point to some extent here. He was contrasting current
buying practices in the U.S. and in Europe, not predicting the future (i.e.
not exactly what I said above). In particular, he mentioned GSM in Europe
and its success... of course, that doesn't count as strong encryption with
the keys evidently being no better than 40 bits worth, but it's a lot
better than calling in the clear from your cellular phone. He indicated
that Europe has embraced GSM and the US has not (yet) embraced anything
equivalent (about which more below).

Clipper wasn't a fiasco from the gov't's point of view if you look at what
it prevented rather than what it achieved. By now the DES-based AT&T
encryption box might be the US standard if the Gov't hadn't intervened by
"incentivizing" them around the time of the Clipper roll-out. It was
ready to go and was already in production when Clipper got rushed up. As
it is there is now no standard and most traffic is still in clear. If
this doesn't reflect a credible and <practical> understanding of how the
market works, what would? Of course this one can't completely be laid at
NSA's door, but it's convenient to think of them as the fount of US crypto
