So far, President Donald Trump's second term in office has been characterized by antagonism to allied nations. In just two months, Trump has shown hostility to the NATO defense alliance while gleefully pursuing a trade war against Canada and Mexico by imposing double-digit tariffs on the two largest purchasers of U.S. goods for specious reasons only to then agree to a pause, before repeating the cycle all over again.

One side effect of Trump's brash, undiplomatic attitude is that some allied nations may back out of purchasing F-35 fighter jets from the U.S., the latest indignity in a program that has infamously become a years-long boondoggle.
