Republicans pilloried Hillary Clinton for what they claimed was her inadequate attention to security as secretary of state in the months before the deadly 2012 attacks in Benghazi, Libya. Congress even passed legislation mandating that the department's top security official have unrestricted access to the secretary of state. But in his first nine months in office, [Secretary of State Rex] Tillerson turned down repeated and sometimes urgent requests from the department's security staff to brief him. Mr. Tillerson, a former chief executive of Exxon Mobil, has made no secret of his belief that the State Department is a bloated bureaucracy. Even before Mr. Tillerson was confirmed, his staff fired six of the State Department's top career diplomats. None were given any reason for their dismissals. Since he decided before even arriving at the State Department to slash its budget by 31 percent ... Mr. Tillerson has frozen most hiring and recently offered a $25,000 buyout in hopes of pushing nearly 2,000 career diplomats and civil servants to leave by October 2018. The number of those with the department's top two ranks of career ambassador and career minister - equivalent to four- and three-star generals - will have been cut in half by Dec. 1, from 39 to 19. "The United States is at the center of every crisis around the world, and you simply cannot be effective if you don't have assistant secretaries and ambassadors in place," said R. Nicholas Burns, a retired career diplomat who was an under secretary of state. "It shows a disdain for diplomacy."
