The United States has urged India to consider American energy supplies as an alternative to Russian oil, with US Deputy Secretary of State Christopher Landau saying there is no “better alternative” than the US.

Speaking during the Raisina Dialogue in New Delhi on Thursday, Landau suggested that India should explore other sources of energy while responding to a question about the country’s continued purchases of Russian crude.

“I hope you are looking for alternate sources… You can’t have a better alternative than the USA,” he said during a session titled Power, Purpose, and Partnerships: American Foreign Policy in a New Era.

Energy concerns amid regional tensions

Landau’s remarks come as global energy markets face uncertainty due to the ongoing Iran conflict, which has raised concerns about possible supply disruptions in the Middle East.

Industry sources indicate that Russia is prepared to redirect crude shipments to India to compensate for potential supply interruptions. Nearly 9.5 million barrels of Russian crude are currently on vessels near Indian waters and could reach domestic refineries in the coming weeks.

India significantly increased its purchases of Russian oil after the Russia-Ukraine war began in 2022, taking advantage of discounted crude and becoming one of Moscow’s major buyers. Western governments have frequently criticised the trade, arguing that it helps finance Russia’s military campaign.

India’s energy security also faces logistical challenges. Around 40 percent of the country’s crude imports move through the Strait of Hormuz, a vital maritime route for global oil shipments. Any disruption in the region could affect supplies to Indian refineries.

Because of this risk, refiners in India are reportedly exploring alternative sources if disruptions in the region continue for more than 10 to 15 days.

Trade ties and strategic relations

The comments come shortly after India and the United States announced a trade agreement aimed at expanding economic cooperation.

Following the announcement, the White House indicated that tariffs on Indian goods could be increased if New Delhi resumed large-scale purchases of Russian oil. India, however, has not officially confirmed any decision to halt Russian crude imports.

Russia has also hinted at potential moves in global energy markets. President Vladimir Putin recently said Moscow could consider halting gas supplies to Europe amid rising energy prices linked to the crisis.

‘America First doesn’t mean America alone’

During his address, Landau defended the “America First” foreign policy approach under US President Donald Trump, stating that it should not be interpreted as isolationist.

“America First doesn’t mean America alone,” he said, adding that Washington expects other countries to pursue their own interests as well.

“Our foreign policy is focused on advancing US interests. We are not a charity,” he added.

Referring to the leadership in both countries, Landau said Trump would aim to “make America great again” while expecting Prime Minister Narendra Modi to focus on strengthening India.

He also described the current period as an important phase in the relationship between the two countries.

“This century is going to see the rise of India. It is in our interest to be partners,” he said, noting that Washington closely follows India’s economic growth and views the relationship as strategically important.

Landau also expressed optimism about ongoing trade negotiations between the two countries, saying the agreement is “almost at the finishing line” and that the US is eager to expand economic engagement with India.

At the same time, he cautioned that Washington does not want to repeat past strategic miscalculations.

“We are not going to make the same mistake with India which we made with China 20 years ago,” he said.

US stance on Middle East tensions

Addressing the broader conflict in the Middle East, Landau said Washington’s priority is to ensure that instability in the region does not threaten global security.

He reiterated the US position on Iran’s nuclear ambitions, stating that Washington had repeatedly warned Tehran against developing nuclear weapons.

“We tried hard to explain our red line to Iran, which is no development of a nuclear weapon,” he said, adding that the US believed diplomacy had not been successful.

Landau also said the future of Iran’s leadership ultimately lies with its citizens.

“Ultimately, the Iranian people will have to decide who their leadership is going to be,” he said.

At least 87 people have been killed after a United States submarine torpedoed an Iranian warship in the Indian Ocean, according to reports by media. The vessel, identified as IRIS Dena, had recently participated in a multinational naval exercise in India before the incident occurred.

The Iranian frigate, a Moudge-class warship, had taken part in the MILAN naval exercise earlier this year. After completing the exercise and beginning its return journey, the vessel was reportedly attacked by a US submarine while sailing in international waters.

US Defence Secretary Pete Hegseth confirmed that an American submarine carried out the strike. Speaking to reporters, he described the attack as proof of the United States’ ability to project military power across the globe amid its ongoing conflict with Iran.

“An American submarine sunk an Iranian warship that thought it was safe in international waters. Instead, it was sunk by a torpedo,” Hegseth said.

Video of strike released by US

Following the attack, the US Department of War released a black-and-white video showing what appeared to be footage from a submarine periscope followed by a distant explosion. The release of near real-time visuals from a submarine attack is considered unusual and highlights changing practices in wartime information sharing.

Military observers noted that the Iranian vessel likely did not detect the US submarine, even though it was operating at periscope depth. Analysts say this suggests a high level of stealth and tactical capability on the part of the American submarine.

Warship had recently visited India

IRIS Dena had earlier travelled to India to participate in the MILAN 2026 naval exercise, one of the largest multilateral maritime drills in the Indo-Pacific region. The exercise brings together navies from several countries to improve cooperation, maritime awareness and coordinated response to security challenges.

According to a statement issued by the Indian Navy on February 16, the harbour and sea phases of MILAN included complex maritime operations such as anti-submarine warfare, air defence exercises and search-and-rescue missions.

It remains unclear whether the US submarine had been monitoring the Iranian ship during its journey to and from the exercise. Defence experts believe it is possible that the submarine tracked the vessel throughout its voyage for intelligence purposes, a practice that is common among naval forces.

Bodies recovered near Sri Lanka

Officials from the Sri Lankan Navy said that 87 bodies have been recovered so far following the sinking of the frigate near Sri Lanka’s coast. Rescue operations are continuing as search teams attempt to locate missing sailors.

Authorities said 32 survivors have been rescued, while 61 crew members are still reported missing.

First torpedo sinking since World War II

Hegseth described the operation as a “quiet death” and said it marked the first time since World War II that the United States has sunk an enemy vessel using a torpedo.

“Like in that war, we are fighting to win,” he said.

According to the Pentagon, a key objective of the ongoing US-Israeli war against Iran is to neutralise Iran’s naval capabilities.

India has rejected claims circulating online that the United States used Indian ports to carry out strikes on Iran, calling the assertion baseless and fabricated.

The clarification came after a video featuring former US Army Colonel Douglas Macgregor began circulating widely on social media. In the interview with a US-based channel, he suggested that American forces were relying on Indian naval bases as part of their military operations against Iran.

Responding to the remarks, the Ministry of External Affairs (MEA) stated that the claims were incorrect.

The MEA’s FactCheck account said that the statements being made on the channel were “fake and false”.

“We caution you against such baseless and fabricated comments,” the ministry said in a post on X on Wednesday.

Tensions escalate in Middle East conflict

India’s response comes amid escalating tensions in the Middle East following a conflict involving the United States, Israel and Iran.

The region was thrown into turmoil after the US and Israel carried out joint strikes on Iran on Saturday, which resulted in the death of Iran’s 86-year-old Supreme Leader Ayatollah Ali Khamenei.

Iran later retaliated by launching missiles targeting Israel as well as American military bases located in Gulf countries.

In another development during the conflict, an American submarine fired a torpedo that sank an Iranian warship in the Indian Ocean on Tuesday night. The vessel, IRIS Dena, had been on a friendly visit to India when it was hit. The attack reportedly left 87 people dead and marked the first instance since World War II in which an American submarine targeted a surface vessel.

The conflict has now entered its sixth day, with tensions continuing to remain high across the region.

Reports suggest that more than 1,000 people have been killed in Iran so far, while about a dozen deaths have been reported in Israel. At least six US troops are also said to have been killed during the fighting.

US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu have defended the strikes on Iran, saying the action was taken because Iran posed an imminent threat.

“If we didn’t do it first, they would have done it to Israel and give us a shot, if that was possible,” Trump said.
