>>I'd say he tries to pacify the Kindergarten - which is easier if he is sounding off against Trump as well, although far less than before election and far less than some european "diplomats"
The Obamas were highly critical of Trump before their fellow citizens gave him a mandate. Now that he has the mandate, Trump has said he'd like to pick Obama's brains about a few things- but actually Trump doesn't have to respond to anybody unless he thinks they have something useful to contribute. My pick is that he'll lock any "nattering nabobs of negativism" in their own echo chamber so he can get on with useful work.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
