这是美国总统唐纳德·特朗普的又一番大胆表态：一份典型的夸张风格的布告，声称美国已几乎将伊朗与世界其他地区隔绝。
It was another bold statement from United States President Donald Trump: An edict in his usual inflated style, claiming that the US had almost sealed Iran off from the rest of the world.
“极少东西能进出伊朗！”美国总统周日在其“真相社交”账号上发帖称，此前一天，美国中央司令部（CENTCOM）刚刚宣布了其最新计划，旨在切断德黑兰的军事供应网络。
“Very little gets into, or out of, Iran!” the US president posted on his Truth Social account on Sunday, a day after the US Central Command (CENTCOM) announced its latest plan to choke Tehran’s military supply networks. On Sunday, CENTCOM announced Task Force Iron Gate– a unit targeting land routes and the Caspian Sea, which will aim to prevent Iran from using ground routes to transport advanced weapons and other materials.
周日，中央司令部宣布成立“铁门”特遣队——一个针对陆路和里海航线的单位，旨在防止伊朗利用陆路运输先进武器和其他物资。
Trump’s message on Truth Social claimed that the task force was “in full force and effect” in Iran – and that between this and the US naval blockade of the strategic Strait of Hormuz, the US had virtually cut off what enters and exits the country.
特朗普在“真相社交”上的留言称，该特遣队已在伊朗“全面生效”——加上美国对战略要地霍尔木兹海峡的海上封锁，美国已实际上切断了进出该国的物资。
But analysts say a small intelligence-focused unit cannot seal Iran’s borders or stop its extensive procurement networks without regional cooperation.
但分析人士表示，一个小型情报侧重的单位若无地区合作，无法封锁伊朗边境或阻断其庞大的采购网络。
They did warn, however, that attempts to disrupt these networks could draw neighbouring countries into the conflict and undermine ongoing diplomatic efforts in the US-Israel war on Iran.
不过他们也警告，试图破坏这些网络可能将邻国卷入冲突，并破坏美国与以色列对伊朗战争中正在进行的外交努力。
“I see Task Force Iron Gate as a desperate attempt to extend the American naval blockade into Iran’s continental supply networks without deploying American troops along its borders,” Andreas Krieg, an associate professor of defence studies at King’s College London, told Al Jazeera.
“我认为‘铁门’特遣队是美国绝望地试图将其海上封锁延伸至伊朗的大陆补给网络，而不在其边境部署美军，”伦敦国王学院防务研究副教授安德烈亚斯·克里格对半岛电视台表示。一个“情报融合中心”前美国中东事务副助理国防部长迈克尔·马尔罗伊对半岛电视台表示，“铁门”特遣队旨在弄清“武器系统是如何进入的，如何可能被切断”以及“伊朗是如何运输其能源的”。
An ‘intelligence fusion cell’Task Force Iron Gate aims to find out where “weapons systems are coming in, how they could potentially be cut off” and how “Iran is transporting its energy”, Michael Mulroy, a former US deputy assistant defence secretary for the Middle East, has told Al Jazeera.
总部设在佛罗里达州坦帕的该部队将与其他美国政府机构协调，“防止先进武器系统、两用技术、受制裁物资和非法收入来源跨越伊朗的陆地边境和里海流动”，美国中央司令部表示。
Based in Tampa, Florida, the unit will coordinate with other US government agencies “on preventing the movement of advanced weapons systems, dual-use technologies, sanctioned materials and illegal revenue streams across Iran’s land borders and the Caspian Sea”, CENTCOM has said.
分析人士称，该特遣队可能协调制裁执法、向外国供应商施压，并与伙伴国家合作破坏走私活动。
Analysts said the task force could coordinate sanctions enforcement, pressure foreign suppliers, and work with partner countries to disrupt smuggling.
据英国皇家联合军种研究所军事科学总监马修·萨维尔称，美国的任务将依赖卫星图像、无人机、截获的通讯、金融情报和情报共享的结合。
According to Matthew Savill, director of military sciences at the Royal United Services Institute, the US mission would rely on a combination of satellite imagery, drones, intercepted communications, financial intelligence and intelligence-sharing.
“然后，坦率地说，我预计会动用一些武力——打击或隐蔽的地面行动——以没收组件，无论是由美军还是以色列人实施，”这位分析人士告诉半岛电视台。
“Then, frankly, I would expect some use of force – strikes or discreet ground operations – to confiscate components, whether done by US forces or the Israelis,” the analyst told Al Jazeera.
“如果他们认为两用组件来自西方，他们会想要传递一些情报，并在中东以外施加法律和经济压力……但如果目标是来自俄罗斯和中国的物资，那将更棘手。”虽然美国中央司令部的声明没有明确点出伊朗与俄罗斯的武器贸易，但分析人士说，该部队可被视为试图破坏包括俄罗斯联系在内的供应网络。
“They would want to pass some intelligence on and bring legal and economic pressure to bear outside the Middle East if they think dual-use components are coming from the West … but if the target is supplies from Russia and China, that will be tougher.”While CENTCOM’s announcement did not explicitly identify Iran’s weapons trade with Russia, analysts say the unit could be seen as an attempt to disrupt supply networks that include Russian connections.
美国媒体报道称，俄罗斯已通过里海向伊朗运送无人机组件和炸药。还有说法称，俄罗斯技术可能正在帮助伊朗开发先进超音速巡航导弹。
US media have reported that Russia has sent drone components and explosives to Iran via the Caspian Sea There are also claims that Russian technology could be helping Iran develop advanced supersonic cruise missiles. Krieg agreed the task force would combine methods, but stated that it would operate largely as an “intelligence fusion cell”.
克里格同意特遣队将结合多种方法，但表示它将主要作为一个“情报融合中心”运作。“20个人无法管控数千公里的边境，”他说。
“Twenty people cannot police thousands of kilometres of frontiers,” he said. “The objective is not necessarily to stop every shipment, but to make Iranian military procurement progressively more expensive, slower and riskier,” he added.
“目标不一定是阻止每一批货物，而是让伊朗的军事采购变得越来越昂贵、缓慢和冒险，”他补充道。
The obstacle the US mission will face, however, is political rather than technological, he argued.
然而，他指出，美国任务面临的障碍是政治层面的，而非技术层面。伊朗的邻国将大体上不愿合作。
Iran’s neighbours will be largely unwilling to cooperate. “Iraq offers Washington some leverage, but Iranian-aligned networks remain deeply embedded in its economy and security institutions,” he explained.
他解释说：“伊拉克为华盛顿提供了一些筹码，但亲伊朗网络仍深深植根于其经济和安全机构之中。”
Azerbaijan could cooperate discreetly, while Turkmenistan would be “extremely reluctant” to jeopardise its neutrality or relationships with Russia and China, said the professor.
他说，阿塞拜疆可能会秘密合作，而土库曼斯坦将“极不情愿”冒险损害其中立地位或与俄罗斯和中国的关系。
Pakistan is particularly unlikely to participate openly because it is currently mediating between Washington and Tehran, he added.
他补充说，巴基斯坦公开参与的可能性尤其小，因为它目前正在华盛顿和德黑兰之间进行调解。克里格说，土耳其也几乎没有兴趣让其与伊朗的边境成为另一场对抗的前沿。
Turkiye also has little interest in turning its border with Iran into another confrontation, said Krieg. “Without these countries’ cooperation, Washington can disrupt individual networks but cannot effectively seal Iran’s borders,” he said.
他说：“没有这些国家的合作，华盛顿可以破坏个别网络，但无法有效封锁伊朗的边境。”
Rami Khouri, a public policy fellow at the American University of Beirut and a non-resident senior fellow at the Arab Center Washington DC, has previously told Al Jazeera that Iran’s history as a trading nation for thousands of years makes the US mission near impossible.
贝鲁特美国大学公共政策研究员、阿拉伯中心华盛顿特区非常驻高级研究员拉米·库里此前曾告诉半岛电视台，伊朗作为一个拥有数千年历史的贸易国家，使得美国的任务近乎不可能。
“There’s an enormous web of contacts that Iran has had for thousands of years with traders and partners and allies all over the region, especially in Asia – it’s virtually impossible for the US to seal off every one,” he said.
他说：“伊朗拥有数千年历史，与该地区各地的商人、伙伴和盟友建立了庞大的联系网，尤其是在亚洲——美国几乎不可能封锁其中的每一个。”
“There are people all over the region who have links with Iran, some very close, some just commercial,” he said.
他说：“该地区到处都有与伊朗有联系的人，有些关系非常紧密，有些仅仅是商业往来。”任务蔓延还是任务不可能？
Mission creep or mission impossible?
克里格对任务蔓延的可能性表示担忧——即特遣队的行动可能将战争扩大到新的领域。
Krieg expressed concern about the potential for mission creep — that the task force’s action could widen the war to new arenas.
他说：“情报收集可能迅速转变为要求扣押、关闭边境或对疑似后勤基础设施实施军事打击的压力。”
“Intelligence gathering can quickly become pressure for seizures, border closures or military strikes against suspected logistical infrastructure,” he said.
“这将把美国的经济战延伸至邻国的主权领土。”伊朗的回应可能会采取不对称手段，“在霍尔木兹海峡加大海上胁迫，并可能利用胡塞武装在曼德海峡及沙特阿拉伯周边施加更大压力”，克里格补充道。
“This would extend America’s economic war into the sovereign territory of neighbouring states.”Iran’s response in turn would likely be asymmetrical, “intensifying maritime coercion in Hormuz and potentially using the Houthis to increase pressure around Bab al-Mandeb and Saudi Arabia”, Krieg added.
前美国高级反恐官员乔·肯特也认为，新成立的特遣部队是美国中央司令部试图破坏正在进行的外交努力。
Joe Kent, a former top US counterterrorism official, has also argued that the new task force is an attempt by CENTCOM to subvert ongoing diplomatic efforts.
“这是美国中央司令部在副总统试图与伊朗人谈判时，邀请伊朗升级冲突，”3月因抗议美国对伊朗的战争而辞职的肯特在美国军方宣布后于X平台表示。
“This is CENTCOM inviting Iran to escalate while the vice president is attempting to negotiate with the Iranians,” Kent, who resigned in March in protest against the US’s war on Iran, said on X following the US military’s announcement.
“正如美国中央司令部所称，这是‘通过作战概念（CONOP）制定的政策’，即军方在不公开违抗总统的情况下，寻找方式使战争升级或持续，从而规避白宫的意图。”与此同时，《华尔街日报》报道，美国中央司令部司令布拉德·库珀与国防部长皮特·赫格塞斯等多位官员正向特朗普施压，要求重新对伊朗发动攻击。
“This is, as CENTCOM calls it, ‘policy by CONOP’, when the military finds a way to subvert the White House without blatantly disobeying the President, by taking actions that will ensure a war escalates or perpetuates.”The Wall Street Journal, meanwhile, has reported that CENTCOM chief Brad Cooper is among the many officials, alongside Defense Secretary Pete Hegseth, pressing Trump to renew attacks on Iran.
然而，一些分析人士指出，如果美国无法进入里海、缺乏地面部队或未得到邻国合作，该特遣部队的实际影响将十分有限。
Some analysts, however, argue that without US access to the Caspian Sea, troops on the ground, or cooperation from neighbouring states, the task force will have limited practical impact.
卡塔尔大学当代历史与政治学教授马吉布·兹韦里在接受半岛电视台采访时表示，由于美国在里海缺乏军事存在，这一新倡议可能仅是象征性举措。
Mahjoob Zweiri, a professor of contemporary history and politics at Qatar University, has told Al Jazeera that the new initiative may just be symbolic because of the lack of US military presence on the Caspian Sea.
“美国没有进入该海域的渠道，除非像阿塞拜疆、亚美尼亚等邻国与其合作……而它们并未合作，因为不想惹恼俄罗斯，”兹韦里说。“这需要地面部队，而这不太可能实现。”
“America has no access to the sea, unless some of the neighbouring countries like Azerbaijan or Armenia or others collaborate [with them] … And they’re not collaborating on this because they don’t want to upset Russia,” said Zweiri. “It will require … troops on the ground, and this is unlikely to happen.”
