• President Trump escalates rhetoric, vowing to attack Iran 'very hard' if negotiations fail.
  • Tehran dismisses threats, warns of severe retaliation against any U.S. aggression.
  • Oil prices spike on fears of supply disruption, with Brent crude rising 3%.

Trump's Warning and Iranian Response

President Donald Trump on Monday threatened to attack Iran "very hard" if the country does not reach a new nuclear deal, according to a person familiar with his remarks. Speaking at a private dinner with donors in Palm Beach, Florida, Trump said, "We're going to be attacking them very hard — harder than they've ever been hit before." The White House did not immediately respond to a request for comment.

Iranian Foreign Minister Mohammad Javad Zarif shot back on Twitter: "Iran has always defended itself proportionally. Any aggression will be met with a devastating response." Iran's mission to the United Nations declined to comment.

Market Reaction and Economic Implications

Oil prices surged on the news, with Brent crude gaining 3.2% to $83.50 per barrel — its highest level in two weeks — as traders priced in a heightened risk of supply disruptions from the Strait of Hormuz. Gold rose 1%, while U.S. stock futures fell 0.5%.

"The market is on edge. A conflict would upend global energy flows and send shockwaves through the economy," said Helima Croft, head of commodity strategy at RBC Capital Markets. Iran accounts for about 3% of global oil production, and the strait handles roughly 20% of the world's petroleum.

Background: Abandoning Diplomacy?

Trump withdrew the U.S. from the 2015 nuclear deal in 2018 and imposed crippling sanctions, but recent efforts to restart talks have stalled. The president's latest ultimatum suggests a shift away from diplomacy toward military action — a position that could alienate European allies who have urged restraint.

"This isn't a bluff — the president is serious about using force," said a former senior administration official who spoke on condition of anonymity to discuss internal thinking. "He sees this as leverage to force Iran to capitulate."

Analysts warn that without a negotiated solution, the U.S. and Iran risk sliding into a direct conflict. "Any U.S. strike would likely trigger Iranian retaliation against U.S. assets in the region and allies like Israel," said Trita Parsi of the Quincy Institute.

Future Outlook

Talks are expected to continue through intermediaries in Oman, but the window for a peaceful resolution appears to be narrowing. A European diplomat involved in the discussions called the situation "alarming" and urged both sides to de-escalate.
