When U.S. intervention might be justified

U.S. intervention in other countries, whether overt or covert, is by no means new, and Daniel Immerwahr notes that the open embrace of expansionism by the President and associates such as Stephen Miller goes back to the nineteenth century. Immerwahr is a professor at Northwestern University and the author of the 2019 best-seller “How to Hide an Empire: A History of the Greater United States.” He discusses Trump’s disdain for international law; tensions between the U.S. and Russia and China; and the historical link between imperialism and appeals to masculine pride.
