US President Donald Trump warned Iran of "something very tough" if Tehran does not accept US demands. Speaking to Israeli Channel 12, Trump said, "Either we reach a deal, or we'll have to do something very tough." His demands include stopping uranium enrichment, cutting links with regional proxies, and limiting ballistic missiles. Trump’s warning comes as Iran’s security chief Ali Larijani met with Oman's Sultan Haitham bin Tariq Al Said to discuss recent US-Iran talks. The US has also sent a "massive armada" to nearby waters, including the USS Abraham Lincoln aircraft carrier. Reports say Trump might send a second carrier to the Middle East. The military buildup has raised fears of a US strike on Iran. On Monday, the US warned commercial ships to stay away from Iranian waters. Since January, Trump has pushed strong pressure on Iran, stating the US military is "locked and loaded and ready to go." He compared the Iran situation to Venezuela, where the US carried out a military operation in January. Trump’s administration demands an end to Iran’s nuclear activities and missile stockpiles. He withdrew the US from the 2015 nuclear deal during his first term and resumed a "maximum pressure" campaign after starting a second term in 2025. In June last year, Trump authorized strikes on Iranian nuclear sites during an Iran-Israel conflict. His current threats come amid ongoing anti-government protests in Iran, where security forces have violently cracked down on demonstrators. Thousands reportedly died, and the government blames foreign powers like the US and Israel for backing protesters. While Trump claimed he might "come to their rescue," no direct US intervention has taken place. Analysts say strikes would focus on cutting Iran's military power rather than helping protesters. Despite harsh repression, Tehran insists its actions were against violent armed groups within the protests. The tense standoff keeps the region on edge, with potential US-Iran conflict looming if diplomacy fails.
