US ramps up Iran pressure as officials warn blockade impact could take months

US officials warn Iran may take months to yield under a naval blockade, despite Trump saying the war is near an end, with talks stalled and demands on uranium enrichment still far apart.

Summary:

• Trump says the Iran war is “very close to over,” but negotiations remain stalled with wide gaps between both sides.
• The US is pressing for a 20-year enrichment freeze and removal of uranium, while Iran is offering far less.
• Officials and analysts warn Iran could take months or longer to feel enough economic pain from the blockade to concede.
• The US is prepared to sustain the naval blockade indefinitely, though it may strain military resources.
• Talks via Pakistan have yielded no breakthrough, with both sides still far apart.
• Internal and external pressures are building, including risks to global energy flows and US domestic politics.

The United States is intensifying economic and military pressure on Iran through a naval blockade, even as President Donald Trump signals confidence that the war is nearing its end, highlighting a growing disconnect between political messaging and the realities of negotiation.

Trump has framed the conflict as close to resolution, suggesting Iran is eager to strike a deal. However, recent talks have produced little progress, with both sides maintaining firm and largely incompatible positions. Washington is demanding that Iran freeze uranium enrichment for at least 20 years and remove enriched material from its territory, while Tehran has offered only a shorter-term freeze and insists on retaining its stockpile.

Despite the administration’s optimism, officials and analysts caution that the blockade strategy may take significant time to have its intended effect. Some estimate it could take months or longer (WSJ, gated) before economic pressure meaningfully weakens Iran’s negotiating position, underscoring the risk of a prolonged standoff.

The US military appears prepared for that scenario. A senior official indicated the Navy could maintain the blockade indefinitely, although concerns remain that doing so would strain resources and reduce US flexibility in other strategic theatres such as the Pacific.

Meanwhile, diplomatic efforts remain in limbo. Vice President JD Vance is on standby to return to Pakistan for further talks, but no concrete plans have been set following earlier discussions that ended without breakthroughs.

Complicating matters further, Iran’s leadership has signalled resistance to pressure tactics, while hardline elements within the regime appear to be gaining influence following recent military losses. At the same time, regional allies such as Saudi Arabia are urging caution, warning that escalation could spill over into broader disruptions across key global energy routes.

For now, the US strategy hinges on whether sustained pressure can force concessions—but the timeline for that outcome remains highly uncertain.

The “months-long” pressure timeline suggest expectations of a prolonged energy risk premium. Oil volatility and shipping disruptions remain key, while any delay in a deal extends upside risks to inflation and global growth uncertainty.
