Max Boot, a lifelong conservative who advised three Republican Presidential candidates on foreign policy, keeps a folder labelled “Trump Stupidity File” on his computer. It’s next to his “Trump Lies” file. “Not sure which is larger at this point,” he told me this week. “It’s neck-and-neck.”

Six months into the Trump era, foreign-policy officials from eight past Administrations told me they are aghast that the President is still so witless about the world. “He seems as clueless today as he was on January 20th,” Boot, who is now a senior fellow at the Council on Foreign Relations, said. Trump’s painful public gaffes, they warn, indicate that he’s not reading, retaining, or listening to his Presidential briefings. And the newbie excuse no longer flies.

“Trump has an appalling ignorance of the current world, of history, of previous American engagement, of what former Presidents thought and did,” Geoffrey Kemp, who worked at the Pentagon during the Ford Administration and at the National Security Council during the Reagan Administration, reflected. “He has an almost studious rejection of the type of in-depth knowledge that virtually all of his predecessors eventually gained or had views on.”

Criticism of Donald Trump among Democrats who served in senior national-security positions is predictable and rife. But Republicans—who are historically ambitious on foreign policy—are particularly pained by the President’s missteps and misstatements. So are former senior intelligence officials who have avoided publicly criticizing Presidents until now.
