Iranian Foreign Minister Abbas Araghchi, Kevin Hassett, Sen. Mark Warner

<p>This week on Face the Nation, the consequences of the war in Iran are increasingly reverberating across the globe. The world's oil supply is under intensifying pressure as Iran threatens to blow up tankers in the Strait of Hormuz, and the U.S. strikes back at the heart of Iran's critical oil hub. President Trump is now asking U.S. allies to send warships to the region to help keep the Strait open as Tehran doubles down on its blockade. We get the latest from Iran's foreign minister Abbas Araghchi. Meanwhile, the pain from the oil supply shock is beginning to hit Americans at the gas pump. We ask President Trump's top economic adviser Kevin Hassett what the administration can do to lower energy prices. The top Democrat on the Intelligence Committee Senator Mark Warner and Texas Republican Congressman Dan Crenshaw also join us. Plus, there were three violent attacks in the U.S. last week against the backdrop of global conflict.  How safe are we in the homeland? We get analysis from our panel of experts, including former counterterrorism official Samantha Vinograd, former CIA operative Jonny Gannon and energy policy expert Kevin Book.</p>
