US President Donald Trump has issued a sharp warning to Iran just ahead of high-stakes negotiations, signalling that the strategic Strait of Hormuz could reopen soon. Trump claimed the vital global shipping route would resume automatically and warned Tehran has limited leverage beyond the temporary disruption of international waterways. As US negotiators prepare to meet Iranian officials, Washington has also reloaded warships, raising the possibility of renewed strikes if talks collapse. Iran, meanwhile, is demanding sanctions relief, an end to Israeli operations in Lebanon, and the unfreezing of assets before negotiations proceed.
