agree, and he will be out there alone. and i don't think putin wants to in a sense publicly nail him to the wall in a set of verbal arguments at the present time. it's not in putin's interests particularly if he's doing well. ian has pointed out that. i think it is extremely unusual to do that. i do know that in the oval office, there are often meetings with heads of state in which part of the meeting is a group meeting, and part of the meeting is a one-on-one with interpreters if that's necessary. and that's obviously to settle carefully prepared business, often worked up in advance, and very much part and parcel of a government clearance process in which it says, mr. president, we recommend you do this. the president usually says, yes, i agree, or i'm going to go do something else, go prepare that for me. but unprepared. and at this stage unverifiable. and very uncertain set of relationships with russia has its dangers. i think one needs to be concerned about that.
