Mihir Sharma认为，美国潜舰击沉伊朗海军舰艇 IRIS Dena，不只是一次战术事件，而是一次战略讯号。该舰在距离伊朗本土约3,200公里（2,000英里）、距离斯里兰卡水域约13公里（7海里）处沉没。这两个数字使亚洲各国更在意美国选择何时、何地动武，而不是仅仅在意华府是否在法律上有权打击潜在威胁。

作者强调，IRIS Dena 刚离开由印度主办、共有73国参与的 Milan 2026 演习，其中也包括美国海军。这使攻击在政治上尤其刺眼：印度被迫辩称自己没有义务保护或为宾客报复，但这种说法只在技术与法律上成立，并未消除道德与政治上的难堪。对 Narendra Modi 而言，这进一步叠加了近期贸易让步、区域战争风险、能源成本上升与侨民受困等压力。

文章的核心判断是，美国此举正在削弱亚洲对其可靠性的信心。斯里兰卡总统甚至表示，另一艘未武装伊朗支援舰不能停靠可伦坡附近，因为那会推高海上保险成本。作者据此推论，若美国让伙伴相信其会滥用基地、港口与飞越权等后勤便利，那么即使军费高出他国10倍，仍无法凭空制造港湾与机场；Dena 的沉没也连带动摇了这种信任前提。

Mihir Sharma argues that the US submarine sinking of the Iranian navy ship IRIS Dena was not just a tactical event but a strategic signal. The ship went down about 3,200 kilometers from Iran (2,000 miles) and about 13 kilometers from Sri Lankan waters (7 nautical miles). Those two figures make Asian countries focus less on Washington's legal justification and more on why the US chose that time and place to use force.

The author stresses that the Dena had just left Milan 2026, an Indian-hosted exercise attended by 73 countries, including the US Navy. That makes the strike politically sharp: India has been forced to argue that it had no duty to defend or avenge its guest, a case that may work technically and legally but not morally or politically. For Narendra Modi, this adds to pressure from recent trade concessions, regional war risk, higher energy costs, and stranded citizens.

The article's central claim is that the episode is weakening Asian confidence in US reliability. Sri Lanka's president even said that another unarmed Iranian support ship could not anchor near Colombo because it would raise maritime insurance costs. From that, the author infers that if partners believe America may misuse logistical access such as bases, ports, and overflight rights, then even spending 10 times more than others cannot create harbors and airfields out of thin air; trust sank with the Dena.
