I think we have hit the worst case scenario in terms of appointments at this point. All the pieces are now in place for a cataclysmic disaster.
President Donald Trump is reshuffling the US National Security Council (NSC), downgrading the military chiefs of staff and giving a regular seat to his chief strategist Steve Bannon.
Mr Bannon, formerly the head of the populist right-wing, Breitbart News website, will join high-level discussions about national security.
The order was signed on Saturday.
The director of national intelligence and the joint chiefs will attend when discussions pertain to their areas.
Under previous administrations, the director and joint chiefs attended all meetings of the NSC’s inner circle, the principals’ committee.
The National Security Council (NSC) is the main group advising the president on national security and foreign affairs.
It is led by retired lieutenant-general Mike Flynn, who was one of Mr Trump’s closest advisers and most ardent supporters during the campaign.
“The security threats facing the United States in the 21st century transcend international boundaries,” Mr Trump’s executive order said.
