So how will the Foreign Affairs boffins analyse what the former Dipton farmer said to the billionaire builder?
If you listen to Prime Minister Bill English, the call he took on the red phone in the back of his Prime Ministerial limo on Waitangi Day from the Oval Office wasn't recorded, which in itself is pretty extraordinary given in politics nuance is everything.
But then, by English's own admission, US President Donald Trump is a man who communicates pretty directly, not bothering with the diplomatic niceties which you'd think would be all the more reason to push the record button.
English says notes were taken, which assumes someone was listening into the call. At one point, recalling the call as Parliament resumed, he initially said it wasn't being eavesdropped on because it was a personal call. But then, in the next breath, he agreed someone was listening in, which would make sense if notes were being taken.
In reality it's nothing more than irritating, trying to establish how these things are handled and how the information in the call could be used to our best advantage. But then Trump's not a man to be held to account for very much that flows through the puckered lips.
