US President Donald Trump has suggested that escalating action against Iran remains a possibility, while declining to disclose what comes next in talks with Tehran. Speaking to reporters at the White House, Trump said they would 'find out' when asked about future steps. When a reporter asked whether a 'massive escalation' was an option, Trump replied that the United States has the ability to do so if it chooses, without elaborating. The remarks come amid ongoing tensions between the two countries. Robert Pape, a political science professor at the University of Chicago, says Trump is caught in an 'escalation trap' with Iran.
