Reports that say that something hasn't happened are always interesting to me, because as we know, there are known knowns: there are things we know we know.
We also know there are known unknowns; that is to say, we know there are some things we do not know. But there are also unknown unknowns: the ones we don't know we don't know.
And if one looks throughout the history of our country and other free countries, it is the latter category that tend to be the difficult ones.
Former defence secretary Donald Rumsfeld will likely be best remembered for the 30 seconds or so that it took those words to come out of his mouth during a media briefing on the lack of evidence linking Iraq to weapons of mass destruction.
As tortured as the words seem to be, Rumsfeld actually describes the fundamental problem that bedevils all of us who are trying to do anything.
It is called uncertainty.
