President Donald Trump on Monday threatened to destroy Iran’s oil infrastructure, power plants and its vital Kharg Island export hub unless Tehran quickly reopens the Strait of Hormuz and reaches a deal with Washington, in a dramatic escalation of pressure as the war entered its fifth week.
In a social media post, Trump said the United States was in “serious discussions” with what he called a “more reasonable” regime in Iran, while warning that if a deal was not reached “shortly” and the strategic waterway was not “immediately” reopened, the United States would “completely obliterate” key Iranian infrastructure.
The warning sharpens a strategy that has increasingly combined military pressure with diplomacy, as Washington seeks to force Tehran to reverse actions that have brought shipping through one of the world’s most important energy chokepoints close to a standstill. The Strait of Hormuz handles roughly a fifth of global crude oil, refined fuel and liquefied natural gas flows, making any prolonged disruption a major threat to the world economy.
Kharg Island has emerged as the centerpiece of that pressure campaign.
Located in the Gulf, the island serves as the heart of Iran’s oil export system and is estimated to handle most of the country’s crude shipments. Any direct attack on the facility would represent a major escalation, not only for Iran’s economy but also for already strained global energy markets. Reuters reported earlier this month that U.S. strikes had already targeted military sites on or around the island, while Trump has repeatedly linked the future of Iran’s energy infrastructure to the reopening of Hormuz.
Iran had not immediately responded publicly to Trump’s latest threat, but earlier on Monday Iranian officials reportedly dismissed U.S. proposals as excessive and denied Washington’s claim that meaningful direct talks were under way. That leaves diplomacy in a fragile position even as intermediaries continue to explore options for de-escalation.
The stakes are high far beyond the battlefield.
Oil prices rose again on Monday, with Brent crude trading above $116 a barrel and heading for what Reuters described as its biggest monthly surge on record. Traders and policymakers are increasingly concerned that the conflict could spill deeper into regional energy infrastructure or trigger wider military involvement, further squeezing already disrupted supply routes.

The pressure is being felt most immediately in Asia, where refiners and importers remain heavily dependent on supplies that normally transit the Strait of Hormuz. PetroChina said on Monday that about 10 percent of its oil and gas supply is linked to the waterway, although it insisted operations remained broadly stable due to diversified sourcing and contingency planning.
Trump’s latest comments also come amid signs that the White House is weighing additional military options.
Reuters has previously reported that the administration has considered sending thousands more U.S. troops to the region as it prepares for possible next steps, including options linked to securing the Strait of Hormuz and Iran’s energy export infrastructure. Such a move would risk dragging Washington into a deeper and potentially more prolonged conflict, a prospect that has stirred debate both at home and among U.S. allies.
For now, the administration appears to be betting that the threat of overwhelming force can compel Iran to back down without requiring a broader ground operation.
But with Tehran showing no sign of retreat and global markets already on edge, the crisis is increasingly becoming not only a military confrontation but also an economic one.
The future of the Strait of Hormuz — and of the world’s energy supply chain — may now hinge on whether threats of destruction can produce the diplomatic breakthrough that weeks of war have so far failed to deliver.
