Human progress has never been shaped by commentators, complainers or cynics.
There is no way you're going to have an event like 9/11 and expect things to remain the same. They killed 3,000 people in New York on that day, and if they could have they would've killed 300,000.
I happen to think it's the politics that makes you electable, but the reason for that is politicians sometimes talk about electability as if it's just a matter of conning the public. Actually, it's a matter of persuading the public, and in my experience, usually, the public gets it right.
In no relationship at the top of any walk of life is it always easy, least of all in politics which matters so much and which is conducted in such a piercing spotlight.
