Pentagon Sees “Increased Potential” for Nuclear Conflict
The possibility that nuclear weapons could be used in regional or global conflicts is growing, said a newly disclosed五角大楼教义出版物关于去年更新的核战争。
“尽管美国为减少核武器在国际事务中的作用并谈判减少核武器数量的努力，但自2010年以来，没有潜在的对手减少了核武器在其国家安全战略中的作用或核武器的数量它字段。相反，他们绝对朝相反的方向移动，”国防部文档said.
“As a result, there is an increased potential for regional conflicts involving nuclear-armed adversaries in several parts of the world and the potential for adversary nuclear escalation in crisis or conflict.”
The publication presents an overview of U.S. nuclear strategy, force structure, targeting and operations. See联合核操作, JP 3-72, April 2020.
The document replaces a 2019 edition titled核行动that was briefly disclosed and then withdrawn from a DoD website. (See“国防部关于核操作的学说出版了，离线，”保密新闻，2019年6月19日。）
当前的文件不再包括一些关于通过核罢工获得“决定性结果”和“冲突中的胜利”的更加不过滤和热情的语言the 2019 version。“总统授权使用核武器”的声明被更改为更加约束的声明：“只有总统才能授权使用核武器”。
同时，已经添加了新材料，包括评估潜在对手的威胁已经增长，即使据说美国的核姿势已经得到了调节：
“虽然美国继续减少the number and salience of nuclear weapons, others, including Russia and China, have moved in the opposite direction. They have added new types of nuclear capabilities to their arsenal, increased the salience of nuclear forces in their strategies and plans, and engaged in increasingly aggressive behavior.”
“Russia’s strategic nuclear modernization has increased, and will continue to increase, its warhead delivery capability, which provides Russia with the ability to rapidly expand its deployed warhead numbers.”
“中国继续增加其核力量的数量，能力和保护。”
“朝鲜继续追求核武器能力，对国际安全和稳定构成了最直接，最可怕的扩散威胁。”
“伊朗发展了越来越长的弹道导弹能力，以及对邻国政府稳定的积极战略和活动，提出了有关其对放弃核武器能力的长期承诺的疑问。”
鉴于越来越多的威胁，国防部说：“在有限的对手核升级后，灵活且有限的美国核反应选择可以在恢复威慑方面发挥重要作用。”
The updated document不断扩大人们对情报在潜在核冲突中的作用的关注，包括“对敌对决策者对福利，成本和约束后果的看法的了解”和“有关对手资产，能力，能力和脆弱性的信息”。施加后伤害评估也需要智能。
国防部说，战略消息传递是阻止冲突的关键，尽管这似乎涉及武力的威胁。“以对手决策者理解的方式传达意图，解决和相关的军事能力的能力至关重要。直接军事手段包括：向前的存在，力投影，主动和被动防御，战略通信/消息传递以及核力量。”
国防部断言，其核指挥和控制系统“准备就绪，可靠，有效地满足当今战略威慑要求。对手可以利用差距或接缝。”也许是这样。
“Possibly the greatest challenge confronting the joint force in a nuclear conflict is how to operate in a post-NUDET [nuclear detonation] radiological environment,” DoD said. “By design, nuclear weapons are highly destructive and have harmful effects that conventional weapons do not have. Commanders must plan for and implement protective measures to mitigate these effects and continue operations.”
联合核操作国防部不可用online public library of Joint Publications。但是，根据《信息自由法》，上周向美国科学家联合会发布了一份2020年4月文件的副本。

The Biden Administration adopted a somewhat conciliatory tone concerning nuclear weapons policy in its March 2021Interim National Security Strategic Guidance：
“As we re-engage the international system, we will address the existential threat posed by nuclear weapons. We will head off costly arms races and re-establish our credibility as a leader in arms control. That is why we moved quickly to extend the New START Treaty with Russia. Where possible, we will also pursue new arms control arrangements. We will take steps to reduce the role of nuclear weapons in our national security strategy, while ensuring our strategic deterrent remains safe, secure, and effective and that our extended deterrence commitments to our allies remain strong and credible.”
But even some simple changes from past practice remain to be accomplished.For now, at least，拜登管理人员仍在遵守特朗普政策of classifying the size of the US nuclear stockpile rather than followingthe Obama policyof disclosing it.
