US President Donald Trump has issued a strong warning to Iran, saying Tehran will face a much bigger US response if it attacks American forces again. Trump made the comments during a phone call with Fox News correspondent Trey Yingst after new US strikes against Iranian targets. He said the latest attack was already a major blow and warned that Iran should not respond with another attack. “If they do respond, they’ll be hit much harder,” Trump said. He then gave an even stronger warning, saying that if the conflict reaches a third round, Iran could be “totally wiped out as a country.” Trump also expressed little confidence in reaching another agreement with Iran. He said the United States had already given Tehran many opportunities to reach a deal but believed an agreement with Iran was not reliable. “I think an agreement with them isn't worth the paper it's written on,” Trump said, adding that the US had given Iran “a lot of chances.” The latest developments have increased fears of a wider conflict in the Middle East. According to reports, the new US strikes followed a period of renewed tensions involving Iranian missile attacks and activity around the Strait of Hormuz. Iran has responded by warning that the United States will regret its latest attacks. The situation could become more dangerous if Iran decides to launch another major attack. A new exchange of strikes could involve military bases, missile sites, ports and other strategic targets. Trump's message is clear: Washington wants Iran to avoid further retaliation, but the US is prepared to respond with greater force if Iran attacks again. The coming hours could be important as both sides decide whether to continue military action or look for a way to reduce tensions.
