And if there’s nothing new to discover, the remembrance of old battles still satisfies. I was amused by Jonathan Powell’s recollection of Mo Mowlam telling him, in relation to Blair’s success in Northern Ireland, that “Tony succeeded because he thought he was fucking Jesus.” After Kosovo, says Robert Harris, Blair “thought he could walk on water” – diagnosing Blair’s Jesus complex runs like a motif through the show. So, too, does the accusation that Blair’s EQ always outstripped his IQ, often made by people who may themselves not be the brains of Britain. Here’s Jeremy Corbyn, look, whose assessment of Blair as “a man in denial” – not an unfair judgment – would be more authoritative if it didn’t come from someone so apparently incapable of internalising lessons from his own clanging defeats. Blair, he says, got himself into a “messianic trench” over Iraq, which is certainly a trench I’d like to see.
