Try thinking of it a little differently. Don't look at Bolton as an independent actor or policy maker. Look at him as that crazy little psycho war-monger who you bring out when you want to freak out out and psychologically destabilize your opponent tand get them to the negotiating table.
It's like Joe Pesci in Casino: they see him coming and they'll stop whatever bullshit scam their running right away. Think Iran nuclear program.
