Chapter 1: What recent deal has the U.S. signed with Iran regarding nuclear weapons?
Live from NPR News, I'm Lakshmi Singh. The U.S. has signed a preliminary deal with Iran that extends their ceasefire for 60 days after President Trump withdrew the United States from the 2050 nuclear accord with Iran in his first term. Questions persist over whether 60 days will be enough time to agree on the terms for ending their war. For Iran, that includes sanctions relief.
For the U.S., assurances Iran abandons nuclear weapons ambitions. Here's Vice President J.D.
Vance. The nuclear weapons program is destroyed. It is gone. If the Iranians decided tomorrow to build a nuclear weapon, they simply don't have the capacity in order to do that.
What we're trying to ensure is they don't rebuild that capacity not just a year from now, two years from now, but many, many years from now, so that our children never have to worry about a state sponsor of terrorism having a nuclear weapon.
Vance leading the White House press briefing today. Two researchers at MIT say they believe they have uncovered how a top-secret Russian missile actually flies. NPR's Jeff Brumfield says Moscow has fired the missile at Ukraine.
In October, Russia launched what it said was a nuclear-powered missile. The missile flew for almost 15 hours, far longer than a regular missile could. Jake Heckla is a researcher at MIT. He says nuclear-powered flight is something that is possible, but wildly expensive and very dangerous. Heckla and his colleague Scott Kemp analyzed the missile.
They believe it's sucking air directly through its nuclear core and spewing radioactivity as it flies. As a result, anyone living near is at enormous risk, potentially. And the missile isn't all that useful, he says. Despite being nuclear-powered, it's relatively slow-moving and easy to shoot down. Jeff Brumfield, NPR News.
Former President Barack Obama and former First Lady Michelle Obama open a new chapter on Chicago's South Side. It's a dream. The impossible dream. Grammy-winning artist Jennifer Hudson among the celebrities and political dignitaries who've turned out today for the dedication of the Obama Presidential Center. Here's NPR's Don Gagne.
It's traditional for former presidents to create a library to house records and documents from their presidency and to highlight their time in the White House. The Obama Center is different. First off, it's not a presidential library, the logic being that records from the Obama era were digital and are accessible online.
