Trump’s enduring legacy is not an institutional structure, but rather a highly toxic culture that has been adopted by many of the president’s followers and will live on after he is gone. Threats against Greenland, NATO, and individual European countries mean that no ally will be able to trust commitments made by the United States again.
Discourse by government officials has been degraded. Cabinet officers and press secretaries know that they don’t have to respond to questions they don’t like because they can simply insult the questioner. And companies will understand that they need to seek individual favors rather than general policies governing entire sectors.
