I find it fascinating how quickly the mood of the world order can change. A week ago we were still necessarily in thrall to an elderly, lying, dishonest, golfing President, worried by the possibility that he might be re-elected. How instantaneously his allies in the press and the world have deserted him, leaving him to give an unattended speech in the car park of a suburban garden centre, while suddenly there is a sense of hope and possibility in the world. It’s legitimate to talk about the perils of climate change, about the benefits of international collaboration, the problems ahead in Ireland if we pursue a hard Brexit, the need to work together. I am enjoying watching Johnson re-invent himself as an internationalist instead of a Trump worshipper.
