Former U.N. Ambassador John Bolton (now appointed National Security advisor) has been a frequent visitor at the White House. He was the preferred candidate to fill the position (replacing H. R. McMaster). He is an extreme hawk, closely tied to the Israel Lobby, who would push hard for war against Iran and also for a hardline position in Syria, one that could lead to direct confrontation with the Syrian Armed Forces and possibly the Russians.
Bolton, who has been described by a former George W. Bush official as “the most dangerous man we had during the entire eight years,” will undoubtedly have a problem in getting confirmed by Congress. He was rejected as U.N. Ambassador, requiring Bush to make a recess appointment which did not need Congressional approval.
