Bad Cop, Bad Cop

It has been widely reported that the Europeans have a scheme in dealing with the White House in which Macron plays the good cop and Merkel, the bad cop.  It clearly doesn’t work in the real world, but at least it makes sense in theory.

The question for today is, if the Trump administration wants to try the same game, how does it work?  There is no shortage of candidates for the bad cop role, but who in this government can plausibly play the good cop?  Trump?  Pompeo?  Bolton?
