File photo: US President Donald TrumpThe 60-day deadline set under a June agreement between the US and Iran to end the war and resolve the dispute over Tehran’s nuclear programme expired on Monday, with the two sides seemingly further apart than before. During the period, President Donald Trump repeatedly warned that America was “locked and loaded” and ready to act if diplomacy failed, fuelling speculation that a military offensive might be launched as soon as the deal window closed.

But as the deadline loomed, Trump signalled a different approach. Describing Washington’s strategy as “low-key”, the US president appeared to ease the immediate pace of military escalation while keeping pressure on Tehran through sanctions, economic measures and the naval blockade.

“We are only semi-negotiating with them. We are just watching Iran with its huge inflation and the fact they have no money,” Trump said.

Trump said Iran was “in very bad shape” economically and claimed Tehran was struggling to find enough money to pay its troops. “It will work out.

It always works out. It's like a chess game,” Trump said.

Washington appears to believe that further economic pressure could force Tehran back to the negotiating table without the need for another major offensive. But “low-key” does not mean the US has backed away from confrontation.

What does ‘low-keying’ meanVice President JD Vance made that clear on Saturday, saying Washington still considers the conflict to be ongoing. “This thing is not over.

It's obviously not at the beginning. We're in the middle of the game, and we're applying a whole host of tools — diplomatic, economic, military tools — to ensure that we get the best outcome for the American people,” Vance told Fox News.

What does ‘low-keying’ mean? Trump's comments came after weeks in which the confrontation appeared to be heading towards another military escalation.

Instead of announcing fresh strikes, he stressed Iran's inflation, economic weakness and difficulty financing its government and military. The approach has three connected elements: economic pressure, the naval blockade and continued diplomatic contacts.

3 pillars of Trump's Iran strategyAccording to Reuters, the administration is considering additional measures against Chinese refiners that buy Iranian oil, Chinese banks involved in Iranian transactions and other entities accused of helping Tehran evade sanctions. More than 1,000 individuals, vessels and aircraft linked to Iran had faced US penalties since the conflict began, while hundreds of billions of dollars in cryptocurrency assets had also been frozen.
