To the Editor:

Re “Trump Details Foreign Policy of Paradoxes” (front page, April 28):

In his major foreign-affairs address on Wednesday, Donald Trump declared that the United States should be “unpredictable, starting now.” Like many of his views in this area, Mr. Trump gets this one exactly backward.

The last thing the world needs is a United States with a radically unpredictable foreign policy, for the same reason that no one needs to share a crowded highway with an unpredictable eighteen-wheeler. Many other countries and institutions formulate their policies with relation to the United States, and a highly erratic American policy would make it impossible for anyone to do so safely.

Mr. Trump’s idea is a call for a state of international chaos that would be dangerous for all concerned, especially the United States.

Note from KBJ: Thank God this man is retired. The United States of America must be feared and respected, not loved or admired. Donald Trump will make America great again.
