Last winter when President-elect Trump tweeted: "United States must greatly strengthen and expand its nuclear capability until such time as the world comes to its senses regarding nukes," the tweet was portrayed as shockingly new and threatening. As president, Trump continues his inflammatory rhetoric. Nonetheless, his nuclear posture is closer to his predecessors than is commonly recognized. It has long been U.S. policy and practice to seek and rely on nuclear superiority. The U.S. led every step in the arms race. That arms race remains the greatest immediate threat to the survival of human civilization and other living beings. That threat has persisted under every president from Truman to Trump.
