> lack of predictability

That's been the problem both times this administration was in power. Some people like to call it 4D Chess (because they don't understand it and their conspiratorial thinking requires there to be "a plot" or "a plan"). The last person to get to the ear of this President is the cause of any new "process" or "policy". It is just whim. Like a dog seeing a squirrel. Something shiny has attracted his attention. And that new squirrel gets chased.
