...NSA seems to be transitioning from a role that was principally involved in nation-state intelligence to a role that is inextricably bound up with law enforcement.

Any organization will act to grow its responsibilities and thus its resources. The USA has no real enemies anymore, and yet these agencies keep growing. Organizations will grow until they encounter some sort of limit.

Is the problem that those who would previously have overseen these agencies and curbed the over-extension you cite no longer want that oversight role, or that they are no longer capable of that oversight role? Barrack Obama talked on the phone all his life just like all other Americans do. His predecessors were the same. What kind of President would be able to cut the NSA budget?

I think reasonable people can debate whether foreign terrorist cells are a real enemy. In the context of NSA surveillance I tend to think "yes", but in the context of airport security I tend to think "no", so it's fair to say I'm ambivalent about terrorism.

But we do have an unmistakable and terrifically serious security problem: proliferation. We spent decades in an arms race with a foreign power that built an arsenal that could end the world several times over. When we won, they disintegrated. Meanwhile, the technology to duplicate atomic weapons technology that we had in the 1950s is improving.

There isn't a lot of foreign surveillance I can imagine having a problem with allocating to the problem of nuclear proliferation.

This would be an excellent priority for our intelligence agencies. Do any of the practices revealed recently seem designed to address that priority? An adversary capable of obtaining, maintaining, and deploying nuclear weapons would probably be capable of secure communications even in the face of PRISM, whether here or overseas. The most likely vector would be something like a submarine or a well-shielded shipping container, but if the plan did require agents in this country I doubt those would be discussing their plans on Facebook or over the phone.

Yes; the FAA 702 extensions that were passed a few years ago specifically mentioned terrorism, proliferation, and espionage.

The set of skills required to carry out an atomic attack and the set of skills required to evade surveillance by NSA are disjoint and seem unlikely to get more correlated. But that's just speculation on my part.

My only point here was that "terrorism" isn't the only threat that NSA is tasked with dealing with.
