Former Indian Foreign Secretary Kanwal Sibal says the US attack on the Iranian frigate IRIS Dena near Sri Lanka demonstrated Washington’s disregard for India’s sensitivities, warning that the war with Iran has expanded beyond West Asia into India’s immediate maritime neighborhood.
“The sinking of the Iranian frigate IRIS Dena by a US submarine in the Indian Ocean has brought the widening conflict with Iran into India’s immediate maritime neighborhood. This is no longer a distant West Asian crisis,” Sibal wrote on X on Friday.
Sibal said the circumstances gave the incident both moral and diplomatic significance for New Delhi.
“That fact gives the episode a moral and diplomatic dimension that cannot simply be ignored. The United States has shown scant regard for Indian sensitivities in carrying out this action so close to our shores,” he said.
Warning that the consequences extend beyond the immediate attack, Sibal said the war between major powers will inevitably spread beyond West Asia into regions vital to India’s interests.
“The larger issue is the progressive spread of the conflict beyond West Asia. Escalation between major powers does not remain geographically contained. It inevitably spills into regions that are vital to India’s security and economic interests,” he wrote.
He added: “Stability in the Indian Ocean, freedom of navigation, and uninterrupted energy flows are not abstract concerns for India. They are core national interests. Any sustained disruption in these waters will have direct and serious consequences for us.”
Sibal said New Delhi now faces the challenge of preserving its strategic autonomy while balancing ties with both Washington and Tehran.
“India now faces the difficult task of preserving its strategic autonomy while managing relations with both Washington and Tehran. Conflicts between other powers that reach our maritime neighborhood leave us with fewer good options and greater exposure,” he wrote.
“The central question is how India protects its interests when the wars of others begin to unfold in its own extended neighborhood. This is no longer a hypothetical problem. It has arrived.”
Sibal also criticized the Indian government following the sinking of the IRIS Dena, writing that, “If India had not invited the Iranian warship to participate in the exercise, it would not have been in that area.”
Referring to the Milan 2026 multinational naval exercise, he said, “Participating ships were not allowed to carry any ammunition,” adding that the Iranian frigate “was unarmed at the time.”
He also said that “the US submarine attack appears to have been planned in advance because Washington was aware of the Iranian warship’s participation in the exercise.”
The IRIS Dena was returning from the Milan 2026 multinational naval exercise, hosted by the Indian Navy with the participation of 72 countries, when it was attacked by a US submarine in the Indian Ocean near Sri Lanka.
Sri Lankan authorities said 32 Iranian sailors were rescued, while the fate of 140 others remained unknown. Iranian media reported that 80 sailors were killed in the attack.
