Yes, it makes some good points. I agree with most of it.
It left out one important word, however.
"Yet."
As in : "It is a conflict that does lend itself to intelligence technology, but it ultimately turns on patience, subtlety and secrecy, none of which are America's strong suits." Yet.
or: " But as the events of the last few days have shown, this is not a strength of the American intelligence community." Yet.
The U.S. in all it's history has rarely, if ever, been truly prepared to fight the war in which it found itself involved.
However, while we historically get off to a rather slow start, we seem to gather momentum very quickly once we, as a nation, determine to win. We do have a reputation for finding a way to get the job done.
So, while I think the article is an accurate presentation of the situation, I'm not sure it will be so accurate 3 years down the road.
We'll learn how to "follow the money". We'll learn how to detect the "cells".
We have to; there's no other option, really. These guys can't be pacified and they won't quit.
