'Put Kharg Island in the crosshairs': Sen Lindsey Graham hits back at Iran's Hormuz grab

WASHINGTON, DC: Senator Lindsey Graham (R-SC) on Saturday, April 18, called for an intensified US military posture against Iran’s maritime infrastructure following reports of IRGC-linked activity targeting international shipping.

In a public statement, Graham urged the White House to reject what he described as pressure tactics tied to the Strait of Hormuz and to maintain, and potentially expand, current enforcement measures.

The remarks come as tensions remain high in the 47-day conflict, with the Strait, through which nearly 20% of the world’s daily oil supply flows, continuing to serve as a central flashpoint.

Iranian-linked claims of exerting control over the waterway have drawn scrutiny from US officials, who say naval operations are ongoing to ensure open passage for commercial vessels.

Lindsey Graham questions reliability of Iranian commitments

Graham questioned the reliability of Iranian commitments in ongoing negotiations, pointing to decades of strained relations since 1979.

“It’s abundantly clear that after 47 years, promises coming from the Iranian regime are worthless,” he said, arguing that any diplomatic agreement should be backed by sustained pressure.

The senator’s position aligns with calls from some lawmakers to maintain the current naval blockade and related economic measures until a final agreement is reached.

The blockade has significantly affected Iranian oil exports, with US officials estimating losses of up to $400 million per day during peak enforcement periods.

While negotiations continue, Graham’s remarks highlight divisions in Washington over how quickly pressure should be eased if progress is made at the diplomatic level.

Graham calls Kharg Island key leverage point

Graham specifically referenced Kharg Island, which handles approximately 90% of Iran’s crude oil exports, as a critical leverage point. He suggested that the US strategy should include the option of targeting key infrastructure if maritime disruptions continue.

US officials have not indicated any change in the current military targeting policy, but analysts note that Kharg Island remains central to Iran’s energy network.

The senator’s comments reflect a view that controlling export capacity is key to influencing Tehran’s negotiating position.

The focus on infrastructure follows reports of attempted disruptions to shipping lanes, which US and allied forces have sought to counter through patrols and clearance operations in the Strait.

Lindsey Graham praises 'brilliantly executed' blockade success

Graham also described the existing blockade as effective, citing its role in limiting Iran’s oil revenue and increasing economic pressure.

Officials tracking the situation have reported that restrictions on exports have sharply reduced income streams tied to energy shipments.

The administration has used maritime enforcement as part of a broader strategy combining military presence with diplomatic engagement.

According to US officials, these measures are intended to create conditions for a negotiated settlement while maintaining operational control of key waterways.

Senator backs continued enforcement amid IRGC-linked concerns

With the April 21 ceasefire deadline approaching, Graham urged the administration to maintain its current course in response to reported IRGC-linked actions.

He said continued enforcement would signal American resolve in protecting global shipping and energy flows.

US officials have reiterated that naval assets remain deployed in the region and are prepared to respond to any threats to commercial traffic. At the same time, diplomatic channels remain active as negotiators work toward a potential agreement.
