President Trump has threatened another U.S. military strike on Iran unless officials in Tehran agree to a new nuclear deal. On Wednesday, Trump wrote on social media that a “massive Armada” was heading to Iran and was prepared to move “with speed and violence, if necessary.” Trump added, “Time is running out, it is truly of the essence!” Iran’s foreign minister promised to respond “immediately and powerfully” to any possible U.S. attack. Following Trump’s threats, European Union foreign ministers imposed new sanctions on Iran, citing the government’s violent crackdown on recent protests.
