埃尔布里奇·科尔比牵头机密项目，扩充短程核能力以威慑中国与俄罗斯

美国驻北约大使马修·惠特克就美伊紧张局势升级发表谈话，此前有报道称中国向德黑兰转移导弹。他还就泽连斯基发出警告后俄罗斯对基辅发动导弹袭击以及乌克兰亟需防空系统一事作出回应。

据报道，五角大楼正在起草一项新的核战略，旨在为唐纳德·特朗普总统提供更多在与中国或俄罗斯发生潜在地区冲突时使用短程核武器的选项。
美国全国广播公司新闻援引五名熟悉该计划的人士的话报道称，由负责政策的国防部副部长埃尔布里奇·科尔比牵头的这项机密项目，将更加重视战术核武器——即旨在地区冲突中打击军事目标的武器系统——而非主要依赖远程战略部队。
报道称，该战略旨在应对中国或俄罗斯袭击美国盟友，而华盛顿必须在不立即升级为大规模战略核交换的情况下确定如何回应的场景。

“我们的看法是，我们需要可靠的核选项，”一名国防部高级官员告诉美国全国广播公司。该官员表示，该战略将“通过向总统提供切实可行且可靠的选项，扩大他的选择空间，从而强化威慑”。
此次战略调整的背景是，美国正面临两个拥有核武器的对手，其武库的能力日益增强。
俄罗斯保留着大量战区核武器，并在乌克兰战争期间多次动用其核能力。与此同时，中国正在迅速扩充和现代化其核力量，美国军方官员越来越多地将其描述为双强核挑战。
战术性或非战略性核武器通常设计用于战区或地区作战，而非远程战略任务。它们通常配备短程运载系统，可能针对军事目标。
但这一标签并不意味着其造成的后果有限：一次核爆炸可能造成大量人员死亡、扩散放射性尘埃，并引发核报复。

国防部尚未公开宣布核使用政策的变动或新的战术核武器项目。福克斯新闻数字频道已联系五角大楼征求评论。
此次核战略评估之际，最后一份限制美俄战略核武库的《新削减战略武器条约》已在六个月前到期，且未达成替代协议，这是几十年来华盛顿和莫斯科首次没有具有约束力的限制措施或核查机制。
该条约并未涵盖战术核武器，而俄罗斯在这一领域拥有显著的数量优势。美国战略司令部今年估计，莫斯科拥有多达2000枚战区核弹头。

长期以来，俄罗斯一直依靠其非战略核武库，部分原因是为了抵消北约的常规军事力量优势。中国不断壮大的核武库给五角大楼规划者带来了额外的挑战，他们需要准备应对与两个核武对手对峙的可能性。
支持五角大楼此次调整的人士认为，为特朗普提供更多可靠的有限反击选项，能够让对手相信华盛顿有能力在不发动全面战略核交换的情况下作出回应，从而强化威慑。

批评者则认为，更加重视用于地区冲突的武器可能会降低使用核武器的门槛，增加有限冲突升级为更广泛核战争的风险。

Elbridge Colby leads classified effort to expand shorter-range nuclear capabilities to deter China and Russia

The Pentagon is drafting a new nuclear strategy aimed at giving President Donald Trump more options for using shorter-range nuclear weapons in a potential regional conflict with China or Russia, according to a report.
The classified effort, led by Under Secretary of War for Policy Elbridge Colby, would put greater emphasis on tactical nuclear weapons — systems intended for use against military targets in a regional conflict — rather than relying primarily on long-range strategic forces, NBC News reported, citing five people familiar with the plans.
The strategy is designed for scenarios in which China or Russia attacks a U.S. ally and Washington must determine how to respond without immediately escalating to a large-scale strategic nuclear exchange, according to the report.

“Our view is that we need credible nuclear options,” a senior War Department official told NBC. The official said the strategy would “expand the President’s option space by providing him with realistic and credible options and therefore strengthen deterrence.”
The reported shift comes as the United States confronts two nuclear-armed adversaries with increasingly capable arsenals.
Russia retains a large stockpile of theater nuclear weapons and has repeatedly invoked its nuclear capabilities during the war in Ukraine. China, meanwhile, is rapidly expanding and modernizing its nuclear forces, creating what U.S. military officials increasingly describe as a two-peer nuclear challenge.
Tactical, or non-strategic, nuclear weapons are generally designed for theater or regional use rather than long-range strategic missions. They often have shorter-range delivery systems and may be intended for military targets.
But the label does not mean they are limited in consequence: a nuclear detonation could kill large numbers of people, spread radioactive fallout and trigger nuclear retaliation.

The War Department has not publicly announced a change in nuclear employment policy or a new tactical nuclear weapons program. Fox News Digital has reached out to the Pentagon for comment.
The review also comes six months after New START, the last treaty limiting U.S. and Russian strategic nuclear arsenals, expired without a replacement, leaving Washington and Moscow without binding limits or inspections for the first time in decades.
The treaty did not cover tactical nuclear weapons, an area in which Russia holds a substantial numerical advantage. U.S. Strategic Command estimated this year that Moscow possesses up to 2,000 theater nuclear warheads.

Russia has long relied on its non-strategic nuclear arsenal in part to offset NATO’s conventional military strength. China’s growing arsenal is adding a separate challenge for Pentagon planners preparing for the possibility of confronting two nuclear-armed competitors.
Supporters of the Pentagon’s reported shift argue that giving Trump more credible limited-response options could strengthen deterrence by convincing an adversary that Washington has ways to respond short of an all-out strategic exchange.

Critics argue that putting greater emphasis on weapons intended for regional use could lower the threshold for nuclear employment and increase the risk that a limited conflict spirals into a broader nuclear war.
