A bit of an aside but it relates to why we offered a state visit in the first place (and it seems it is unpresidented to offer one in the first year of a presidency)
Oliver Letwin on Newsnight said offering was our Ace card and we played it. And he said it in defence of the state visit.   

Careless analogies like that amuse me: any player of Bridge, Whist or similar games will tell you playing the Ace right at the start is the mark of an amateur: you use it later to control the game, not right at the start when your opposite will just give dross in return. And the same here: as remarked above offering a state visit too early weakens your hand, rather than strengthening it
