July 7, 2021U.S. military manual that only recently became public says that the world now faces a higher probability of conflicts involving nuclear weapons. The document points to multiple nuclear weapons systems and policies being pursued by adversaries and potential adversaries as signs that the world is moving away from de-escalation and is instead moving closer to the reality of a nuclear exchange. While the document avoids placing any weight on United States policy in helping to increase the likelihood of nuclear conflict, it does note that the “flexible” nuclear weapons the US has pursued could be used to defend America and its interests in the event of a regional conflict involving nuclear arms.
