President Donald Trump warned Thursday that “bad things” will happen if Iran fails to reach a new nuclear agreement, as the United States positions additional military assets near the Middle East.

“It’s proven to be, over the years, not easy to make a meaningful deal with Iran, and we have to make a meaningful deal. Otherwise, bad things happen,” Trump said, adding that he believes 10 to 15 days is “enough time” for Tehran to come to terms.

The warning comes as the USS Gerald R. Ford aircraft carrier approaches the region, bolstering U.S. strike capacity. According to U.S. officials, the “full forces” needed to carry out potential military action are expected to be in place by mid-March. An additional 50 American combat aircraft, including F-35s, F-22s, and F-16s, have also been ordered to the region.

Iran, meanwhile, conducted annual military drills with Russia in the Gulf of Oman and the Indian Ocean, including live-fire exercises in the strategically vital Strait of Hormuz. Iranian state media reported the exercises were designed to improve operational coordination and military readiness. Tehran also issued rocket-fire warnings to pilots in the area, signaling possible anti-ship missile launches as part of the drill.

Indirect nuclear talks in Geneva have produced little visible progress. Iran has agreed to draft a written proposal responding to U.S. concerns, though no timeline has been publicly announced. The talks remain limited to Tehran’s nuclear program, with Iran rejecting broader U.S. and Israeli demands to curb its missile arsenal and cut ties with militant groups.

Israeli Prime Minister Benjamin Netanyahu said his country is preparing for any scenario and warned that if Iran attacks Israel, it will face consequences “they cannot even imagine.”

European leaders have also taken precautionary steps. Polish Prime Minister Donald Tusk urged citizens to leave Iran immediately, warning evacuation could soon become impossible. Germany confirmed it has relocated non-essential personnel from a military base in northern Iraq amid rising regional tensions.

Iran maintains that its nuclear program is peaceful and says it has not resumed uranium enrichment following last year’s Israeli and U.S. strikes. Trump previously stated those strikes had “obliterated” Iran’s nuclear facilities, though Tehran has barred international inspectors from verifying the full extent of the damage.

With American naval power moving into position and Iran demonstrating military readiness alongside Russia, both sides are signaling resolve, even as a narrow diplomatic window remains open.
