Tony Blair: the defining moment that was 9/11
Maybe this isn't exactly and precisely an example of a changed mind. But it's an excellent description of that moment of insight and clarity that comes with a watershed event whose significance can't be denied (for some, at least).
Tony Blair describes (via Austin Bay) what happened to him on 9/11, and it's remarkably similar to what happened to me, and to so many of us:
...9/11 for me was, 'Right, now I get it. I absolutely get it.' This has been building for a long time. It is like looking at a picture and knowing it was important to understand it, but not quite being able to make out all its contours. And suddenly a light was switched on and you saw the whole picture. It was a defining moment.
He continues, about Britain:
We stood shoulder to shoulder with America because my belief then, and my belief now, is that America was attacked not because it was America - but because it was the repository of the values of the Western world, and it was the main power embodying them. It was an attack on all of us. And I don't mean that in a sentimental way.
