I’d pick Bolton.
Me too. For me, Petraeus is a “Oh hell no!” choice - another potential SecState with a piss-poor security history; Giuliani might have been loyal in his support of Trump from the get-go, but he is and always has been a “What’s good for Rudy” kind of guy; and, as for Romney, don’t trust him as far as I can throw him.
Bolton and Dennis Ross as backup
