一位拥有物理学背景的众议院民主党议员正在警告，美国在进攻行动中缺乏应对伊朗核设施的计划，这令他感到担忧。
周二，在与高级政府官员进行机密简报后，伊利诺伊州民主党众议员比尔·福斯特表示，议员们没有得到一个明确的计划，以确保或中和伊朗储存的浓缩铀。
“我们听说他们从未有过关于那批浓缩铀库存的计划——无论是摧毁它、夺取它还是将其置于国际检查之下，”他说。
特朗普政府公开将美国的干预行动辩护为阻止伊朗发展核武器的必要步骤。
美军已对伊朗发动了1700多个目标的打击，包括弹道导弹发射场、防空系统、海军资产和指挥中心。然而，核心核设施并非此次行动的主要目标。
“在这种情况发生之前，伊朗将非常非常接近能够制造——正如许多观察人士在非机密场合指出的那样——伊朗可以利用这些材料制造少量广岛式核武器，”福斯特告诉福克斯新闻数字频道。“不是那种你可以装在导弹上的核武器，但可以通过其他多种方式运送，而且很难阻止。”
福斯特指的是伊朗的高浓缩铀储备，这种材料如果被武器化，可能用于制造核爆炸装置。
专家指出，制造适合弹道导弹的小型核弹头在技术上非常复杂，需要先进的工程技术。但一种更简单、更大的核装置——基本概念类似于1945年美国投放在日本广岛的炸弹——不需要小型化就能装在导弹上。这种装置无法通过远程火箭运送，但理论上可以通过其他方式运输。
福斯特认为，控制伊朗的核材料（其中大部分埋藏在地下深处）可能需要美军进入伊朗。
最近的卫星图像显示，伊朗纳坦兹浓缩铀设施的辅助建筑和入口受到破坏，尽管关键核设施的最深地下基础设施尚未被确认是当前行动的主要目标。
美国和国际官员此前已承认，虽然打击可以破坏浓缩铀基础设施，但储存在地下的浓缩铀库存可能保持完好，除非进行物理安全或移走，否则可能仍可回收。
“你必须带着靴子进入那里，抓起一堆设备，”福斯特说。“你必须深入地下设施，为此要牺牲很多士兵的生命。
“他们不愿意这样做，或者他们决定不这样做，或者他们认为这是不可能的。无论如何，他们没有向我们提出任何能够实际控制这些材料的计划。”
他认为，如果不确保核材料安全，军事行动可能会比外交谈判更让伊朗接近核武器。
“关于阿亚图拉的唯一积极之处是，他曾发布过反对制造核武器的宗教法令，”福斯特说。“谁知道下一代阿亚图拉会有什么想法？他们将面临来自伊斯兰革命卫队的巨大压力，而该卫队并不那么反对拥有核武器。”
被美以联合行动杀死的阿亚图拉阿里·哈梅内伊此前曾发布过反对寻求核武器的宗教法令。分析人士长期以来一直在争论这一裁决的约束力和持久性。
在周三的白宫简报会上，新闻秘书卡罗琳·莱维特表示，政府认为伊朗“想要制造核武器来对抗美国及其盟友”，将打击描述为防止德黑兰推进核野心的必要措施。
“美国军方拥有足够多的弹药、弹药和武器库存来实现特朗普总统提出的‘史诗般的愤怒行动’目标——甚至更多。尽管如此，特朗普总统一直高度重视加强我们的武装部队，他将继续呼吁国防承包商更快地制造美国制造的武器，这些武器是世界上最好的，”她在给福克斯新闻数字频道的后续声明中说。
导弹压制战略面临“数学难题”
高级政府官员强调，当前行动阶段旨在削弱伊朗用导弹、无人机和海军资产投射力量的能力。
国防部长彼得·赫格塞斯强调打击伊朗的弹道导弹系统、防空系统和海军能力，称这是为了削弱德黑兰威胁美军和地区盟友的常规手段。
国务卿马尔科·卢比奥同样表示，美国正在努力“系统性地拆解”伊朗的导弹计划，使其无法“躲在”导弹计划后面发展核武器。
虽然干预行动的更广泛理由是防止伊朗拥有核武器，但美军和合作伙伴面临的最紧迫威胁一直是伊朗持续的导弹和无人机发射。政府官员称，伊朗的导弹建设是为了建立一个威慑缓冲区，保护其更广泛的战略野心，包括核计划，免受外部攻击。
从机密简报中出来的议员们表示，这场行动在一定程度上成为了一个可持续性问题。
“我们没有无限的供应，”亚利桑那州民主党参议员马克·凯利说，指的是美国及其盟友的拦截器库存。他警告称，这场冲突可能变成一个“数学问题”，即平衡发射量与有限的防空弹药以及在不削弱其他战区战备状态的情况下补充弹药的能力。
“在某个时候——我们可能已经处于这种情况——这变成了一个数学问题，”凯利补充道。
他说，他向国防官员询问了拦截器库存如何补充，以及将弹药转移到中东是否会削弱美军在其他地区的战备状态。
“我们如何重新供应防空弹药？它们将来自哪里？这对其他战区有什么影响？”他说。“目前的数学计算似乎是个问题。”
新泽西州民主党参议员安迪·金表示，他也寻求拦截器库存的明确信息，但没有得到详细答复。
“我对此非常担忧，”金说。“我今天没有得到任何具体信息……类似‘相信我们’的说法对我来说不够。”
然而，共和党人反驳了拦截器供应紧张的说法。
俄克拉荷马州共和党参议员马克韦恩·穆林表示，官员们告诉议员们，美军“状况良好”，驳斥了对短缺的担忧。
前以色列国防官员、国家安全分析师埃胡德·埃拉姆表示，虽然核武器仍然是最严重的长期威胁，但如果情报评估认为伊朗尚未准备好组装核武器，导弹和无人机系统将构成最紧迫的危险。
“只要估计伊朗短期内无法制造核武器，那么重点就会转向导弹和无人机，”埃拉姆说，并指出弹道导弹最终将是任何未来核弹头所必需的。他说，压制移动发射装置、机组人员和指挥网络可以降低伊朗的发射速度，节省拦截器库存，同时削弱德黑兰的整体军事能力。
这种担忧并非理论上的。
在2025年6月激烈的伊朗-以色列冲突期间，据报道美军发射了150多枚“末段高空区域防御系统”（THAAD）拦截弹，约占全球库存的四分之一，同时还发射了大量舰载“标准”导弹拦截器以保护盟友。
分析人士指出，以目前的生产速度，补充爱国者、THAAD和SM-3拦截器等高尖端防空系统可能需要一年多的时间。
五角大楼还在平衡相互竞争的需求。用于保护美军基地和海湾合作伙伴的相同导弹防御系统正在提供给乌克兰，以防御俄罗斯的巡航导弹袭击，这造成了一些分析师所谓的欧洲和中东之间库存的“零和”竞争。
“THAAD导弹的使用是有限度的，”埃拉姆说。“这些不是你可以一夜之间复制的系统。”

Physicist lawmaker warns Iran could build ‘Hiroshima-style’ weapon, says US lacks uranium plan
Rep. Bill Foster says administration presented no plan to secure Iran’s enriched uranium stockpile during classified briefing
By Morgan Phillips

A House Democrat with a background in physics is sounding the alarm over what he views as a lack of a plan to deal with Iran’s nuclear sites during the U.S. offensive campaign.
After a classified briefing Tuesday with top administration officials, Rep. Bill Foster, D-Ill., said lawmakers were not presented with a clear plan to secure or neutralize Iran’s stockpile of enriched uranium.
“We have heard that they never had a plan for that nuclear stockpile of enriched uranium — to destroy that, to seize it or to put it under international inspection,” he said.
The U.S. intervention was publicly justified by the Trump administration as a necessary step to stop Iran from developing a nuclear weapon.
U.S. forces have struck more than 1,700 targets across Iran, including ballistic missile launch sites, air defenses, naval assets and command centers. Core nuclear facilities, however, have not been among the primary targets.
“Until that happens, Iran will be very, very close to making — as many observers have pointed out in a nonclassified situation — Iran can use that material to make a handful of Hiroshima-style nuclear devices,” Foster told Fox News Digital. “Not the sort you can put on a missile, but the sort you can deliver by a number of other ways and are very hard to stop.”
Foster was referring to Iran’s stockpile of highly enriched uranium, material that, if weaponized, could be used to build a nuclear explosive device.
Experts note that building a compact warhead that fits on a ballistic missile is technically complex and requires advanced engineering. But a simpler, larger nuclear device — similar in basic concept to the bomb the U.S. dropped on Hiroshima, Japan, in 1945 — would not need to be miniaturized to fit on a missile. Such a device could not be delivered by long-range rocket but could theoretically be transported by other means.
Foster argued that containing Iran’s nuclear materials, most of which are buried deep underground, would likely require U.S. forces to enter Iran.
Recent satellite imagery shows damage to support buildings and access points at Iran’s Natanz enrichment site, though the deepest underground infrastructure at key nuclear facilities has not been confirmed as a primary target in the current campaign.
U.S. and international officials previously have acknowledged that while strikes can damage enrichment infrastructure, stockpiled enriched uranium stored underground may remain intact and potentially retrievable unless physically secured or removed.
“You have to go in there with boots on the ground and grab a bunch of equipment,” Foster said. “You have to go underground into those facilities and lose a lot of soldiers’ lives doing that.
“They’re unwilling to do that, or they’ve decided not to or they’ve decided it’s impossible. In any case, they did not present to us any plan that would actually get the material under control.”
Without securing the nuclear material, he argued, military operations may push Iran closer to a nuclear weapon than diplomatic negotiations would have.
“The only positive thing about the ayatollah is that he had a fatwa against building nuclear weapons,” Foster said. “Who knows what the next generation of ayatollahs are going to feel? They’re going to be under a lot of pressure from the IRGC, which was not so much against having a nuclear weapon.”
Ayatollah Ali Khamenei, who was killed in the joint U.S.-Israeli operations, had previously issued a fatwa, a religious edict, opposing the pursuit of nuclear weapons. Analysts have long debated how binding or durable that ruling was.
At a White House briefing Wednesday, press secretary Karoline Leavitt said the administration believes Iran “wanted to build nuclear weapons to use against Americans and our allies,” framing the strikes as necessary to prevent Tehran from advancing its nuclear ambitions.
“The US military has more than enough munitions, ammo, and weapons stockpiles to achieve the goals of Operation Epic Fury laid out by President Trump — and beyond. Nevertheless, President Trump has always been intensely focused on strengthen our Armed Forces and he will continue to call on defense contractors to more speedily build American-made weapons, which are the best in the world,” she said in a follow up statement to Fox News Digital.
Missile suppression strategy faces ‘math problem’
Senior administration officials have emphasized that the current phase of the campaign is aimed at dismantling Iran’s ability to project force with missiles, drones and naval assets.
Defense Secretary Pete Hegseth has highlighted strikes on Iran’s ballistic missile systems, air defenses and naval capabilities, describing the effort as a push to degrade the conventional tools Tehran uses to threaten U.S. forces and regional allies.
Secretary of State Marco Rubio similarly has said the United States is working to “systematically take apart” Iran’s missile program, so it could not “hide behind” it to develop a nuclear weapon.
While the broader justification for intervention centered on preventing a nuclear-armed Iran, the most immediate threat facing U.S. troops and partners has been Iran’s ongoing missile and drone launches. Administration officials contend Iran’s missile buildup was meant to create a deterrent buffer, shielding its broader strategic ambitions, including its nuclear program, from outside attack.
Lawmakers emerging from classified briefings said the campaign has become, in part, a question of sustainability.
“We do not have an unlimited supply,” Sen. Mark Kelly, D-Ariz., said of U.S. and allied interceptor inventories. He warned the conflict could become a “math problem,” balancing launch volumes against finite air defense munitions and the ability to replenish them without weakening readiness in other theaters.
“At some point — and we’re probably already in this — this becomes a math problem,” Kelly added.
He said he pressed defense officials on how interceptor stocks are being replenished and whether diverting munitions to the Middle East could strain U.S. readiness elsewhere.
“How can we resupply air defense munitions? Where are they going to come from? How does that affect other theaters?” he said. “The math on this currently seems to be an issue.”
Sen. Andy Kim, D-N.J., said he also sought clarity on interceptor inventories but did not receive detailed answers.
“I am very concerned about that,” Kim said. “I did not get any specificity today. … Something akin to ‘trust us’ is not good enough for me.”
Republicans, however, pushed back on the notion that interceptor supplies are strained.
Sen. Markwayne Mullin, R-Okla., said officials told lawmakers U.S. forces are “in great shape,” dismissing concerns about shortages.
Ehud Eilam, a former Israeli defense official and national security analyst, said that while a nuclear weapon remains the most serious long-term threat, missile and drone systems pose the most immediate danger if intelligence assessments conclude Iran is not on the verge of assembling a device.
“As long as it is estimated Iran cannot produce a nuclear weapon soon, then the focus moves to missiles and drones,” Eilam said, noting that ballistic missiles would ultimately be required to deliver any future nuclear warhead. Suppressing mobile launchers, crews and command networks can reduce Iran’s firing tempo, conserving interceptor supplies while degrading Tehran’s broader military capacity, he said.
The concern is not theoretical.
During the intense June 2025 Iran–Israel conflict, U.S. forces reportedly fired more than 150 Terminal High Altitude Area Defense interceptors, roughly a quarter of the global inventory, along with large numbers of ship-based Standard Missile interceptors to shield allies.
Analysts note that replenishing high-end air defense systems such as Patriot, THAAD and SM-3 interceptors could take more than a year under current production rates.
The Pentagon also is balancing competing demands. The same missile defense systems used to protect U.S. bases and Gulf partners are being supplied to Ukraine to defend against Russian cruise missile attacks, creating what some analysts describe as a “zero-sum” competition for inventory between Europe and the Middle East.
“There is a limit to how many THAAD missiles can be used,” Eilam said. “These are not systems you can reproduce overnight.”
