One of the great things about the human experience is 20/20 hindsight, which we all have.
We can sit at our keyboards and look down on those who make decisions and wonder why they didn't do this or that, based on what we - including them - now know has turned out as a result of doing or not doing something.
Fortunately, the PM does not have the time to wonder what every keyboard numpty is busy doing judging him with that hindsight, he has more important things to do.
Come to think of it, said keyboard numpties aside - so do all the rest of us.
