Scott,

Hey, sure. There's been progress on the training front, not trying to discount that. We're not 'there' yet though.

And JSOC's small teams doing stuff is still tactical or at the very highest operational. They may have an effect that is seen at the strategic level, but that is still only one or at max two elements of national power. IF we were to expand USSOCOM's mission to affect all of the elements of national power, it would only be able to do it in a small region. And if we were to expand it completely, we might as well re-name USSOCOM the "Department of Everything." It might be easier, but again, every other department within the USG would have to sign on to it - as they did the stability operations doctrine.
My point was JSOC is a good prototype. A model that can be used as a starting point for implementing a swarming doctrine across DoD.

As you describe, of course reforming bureaucracy will be a long, arduous process full of compromises - that's the nature of reform. Don't think that's a good reason not to though.
