One thing stands out amid all the chaos, corruption and disorder: the wanton destructiveness of the Trump presidency.

The targets of President Trump’s assaults include the law, higher education, medical research, ethical standards, America’s foreign alliances, free speech, the civil service, religion, the media and much more.

J. Michael Luttig, a former federal appeals court judge appointed by President George H.W. Bush, succinctly described his own view of the Trump presidency, writing by email that there had never

been a U.S. president who I consider even to have been destructive, let alone a president who has intentionally and deliberately set out to destroy literally every institution in America, up to and including American democracy and the rule of law. I even believe he is destroying the American presidency, though I would not say that is intentional and deliberate.

Some of the damage Trump has inflicted can be repaired by future administrations, but repairing relations with American allies, the restoration of lost government expertise and a return to productive research may take years, even with a new and determined president and Congress.

Let’s look at just one target of the administration’s vendetta, medical research. Trump’s attacks include cancellation of thousands of grants, cuts in the share of grants going to universities and hospitals and proposed cuts of 40 percent or more in the budgets of the National Institutes of Health, the Centers for Disease Control and Prevention and the National Science Foundation.

“This is going to completely kneecap biomedical research in this country,” Jennifer Zeitzer, the deputy executive director at the Federation of American Societies for Experimental Biology, told Science magazine. Georges Benjamin, the executive director of the American Public Health Association, warned that cuts will “totally destroy the nation’s public health infrastructure.”

I asked scholars of the presidency to evaluate the scope of Trump’s wreckage. “The gutting of expertise and experience going on right now under the blatantly false pretext of eliminating fraud and waste,” Sean Wilentz, a professor of history at Princeton, wrote by email, “is catastrophic and may never be completely repaired.”
