I found this to be fascinating in terms of understanding Trump and what is going on now.

The Demolition of U.S. Diplomacy


Almost 70 years ago, in the early years of the Cold War, Senator Joseph McCarthy conducted a savage campaign against “disloyalty” in the State Department. Partisan investigators, untethered to evidence or ethics, forced out 81 department employees in the first half of the 1950s. Among them was John Paton Davies, Jr., an accomplished China hand. His sin was to foresee the communist victory in the Chinese Civil War. Davies was subjected to nine security and loyalty investigations, none of which substantiated the paranoid accusation that he was a communist sympathizer. Nevertheless, in a moment of profound political cowardice, Secretary of State John Foster Dulles fired him.

Purging Davies and his colleagues was not only wrong but also foolish. The loss of such expertise blinded American diplomacy on China for a generation and had a chilling effect on the department and its morale. One of the United States’ most distinguished diplomats, George Kennan, was also pushed out of the Foreign Service during this era. He tried to defend Davies, who had served with him in Moscow and on the Policy Planning Staff, to little avail. Years later, Kennan wrote in his memoirs that McCarthy’s onslaught and the department’s failure to defend its employees was the most “sobering and disillusioning” episode of his long career.

That Senator McCarthy’s chief counsel, Roy Cohn, was also Donald Trump’s lawyer and mentor is one of history’s sad ironies. Trump’s scorched-earth tactics, casual relationship with truth, and contempt for career public service bear more than a passing resemblance to the playbook that Cohn wrote for McCarthy. And when Trump cried out for a “new Roy Cohn” to replace the late original, it was hardly a surprise that former New York Mayor Rudy Giuliani appeared—or that he dove into the muck of the Ukraine scandal and agitated for the removal of a career ambassador whose integrity and expertise proved to be an obstruction.
