In March 2017, Robert Jervis of Columbia University wrote that Tillerson "had little impact on the Trump administration so far" and that his influence would continue to wane. That same month, William Inboden of the University of Texas at Austin defended Tillerson, saying he deserves more time. Daniel W. Drezner of the Fletcher School of Law and Diplomacy at Tufts University was highly critical of Tillerson, calling him an "unmitigated disaster", and "the most incompetent Secretary of State in modern history". Elliot Cohen of Johns Hopkins University said Tillerson might be one of the weakest secretaries of state in American history. Elizabeth Saunders of George Washington University said Tillerson's tenure had damaged the Department of State "for a generation" and decreased America's ability to respond to major crisis.
