Iran and the US lean into gunboat diplomacy as nuclear talks hang in balance

Iran and the United States are both applying naval pressure to the talks over Tehran's nuclear program. Tehran held drills Thursday with Russia. Meanwhile, the Americans brought another aircraft carrier closer to the Mideast, the USS Gerald R. Ford. The movements of additional American warships and airplanes to the region don’t guarantee a U.S. strike on Iran. But it does give President Donald Trump the ability to carry out one should he choose to do so. Meanwhile, Iran struggles with unrest at home following its deadly crackdown on protests. Mourners are holding ceremonies honoring their dead.
