Bolton's philosophy is "take the conflict to the enemy and devastate them utterly". The new policies are leaning toward brinkmanship and deal-making, so Pompeo et will take the lead.
Hard-line policies in international affairs is necessary when sending a message. That message was sent effectively with the destruction of ISIS (largely engineered by Sebastian Gorka, who still supports the administration 1000%).
Bolton will do well in the private sector. Or he could do Flanders impersonations at parties.
