After western powers reached a deal to limit Iran’s nuclear program, what’s next? Today on River to River, guest host Ben Stanton sits down with political science experts Tim Hagle, of the University of Iowa, and Wayne Moyer, of Grinnell College. They talk about the deal and why it’s being met with skepticism by Israel, and some in Congress. They also discuss what happens after one party in the U.S. Senate uses a so-called nuclear option.
