I've a funny feeling that he has one last big thing/incident in him. He strikes me as the sort of guy that will want to go out with a bang. If I was in Iran now I'd be twitching a bit as it seems to me that he has always wanted to do something to slow down their nuclear development. With the Democrats and especially Biden coming in there is now no way that the US would launch a pre-emptive strike and so with his time in the big seat finishing soon I can see something like that being his swansong.
