As Trump's National Security Adviser though, Bolton was foolishly combative with Trump, with too many disagreements being in the nature of an employee thinking the boss to be an inexperienced dope and therefore subject to countermand by the employee. More broadly, Bolton seemed to be both more hawkish than Trump and unable to accept Trump's real estate hustler manner of negotiation and efforts to keep adversaries off-balance and guessing at his intentions.
If more self-disciplined and less arrogant, Bolton would have put aside his personal opinions and might have become a successful adviser and executor for Trump, like Secretary of State John Hay with Teddy Roosevelt. Similarly, Kissinger sometimes clashed with or was exasperated with Nixon or criticized him in private, but he cleverly used Nixon's reputation for toughness and daring moves as a lever to secure agreements with foreign counterparts.
Yup.
