Bolton, who has long advocated an expansive military presence around the world, has become a staunch internal foe of an emerging peace deal aimed at ending America’s longest war, the officials said.
His opposition to the diplomatic effort in Afghanistan has irritated President Trump, these officials said, and led aides to leave the National Security Council out of sensitive discussions about the agreement.
