It takes a while to catch on that manipulative and abusive people are in fact, manipulative and abusive. Trump has excelled at getting people on all sides to show their true colors.
Or, President Trump understood Bolton was known to be manipulative and abusive.
President Trump could use someone like Bolton in a good cop/bad cop routine.
President Trump could have Bolton in a negotiating room representing the dark alternative. All the while, President Trump would listen to Bolton then immediately disregard everything said.
MAYBE, Bolton figured out he was merely a piece in a negotiation framework and is now pissed off?????????????
